Ive dealt with this error at AWS. It’s a unit error. In my case we _meant_ to charge like 5¢/GB, but missed the unit (GB), and then the billing system defaults to bytes. 5¢ per Byte of data transferred meant some customers were seeing MM bills within hours. Got paged by support around 2am, had it fixed and amendments issues by 3-4am, apology emails shortly after.

Services emit metering values that arent directly tied to prices. Every SKU/line item is defined in a “pricing plan”, with a unit type, regions, and price per unit. The metering records are joined to a pricing plan based on account id, region, sku, etc. mess up the unit type in the pricing plan and the metering data conversion doesnt work, and you get crazy bills.

    There will have been tests, but there will have been missing end-to-end tests. Test 1 will verify that the new system/product emits billing entries in some expected way ("We did 100 bytes of operations and we see we called the billing system for 100 bytes of stuff, yay, test pass"). Test 2 will be in the billing system ("We provide an incoming bill for SKU#12345 for 100 gigabyte-units and we see it costs $17, yay, test passes"). But they won't test the two things together because it will be harder to do and the teams will have different management chains. Seen it happen several times at several companies. Somebody will have said at some point "we should actually have the tests charge money" and somebody else will have said "well we can't have the tests actually charge money, that's a legal/accounting problem, it might even be a crime" and then nobody would have asked what the next best thing was.

      You overestimate how much people give shits at big techs like Amazon. When literally everything is driven with sticks instead of carrots, the work culture does not invite employees to proactively care about product quality.

      You'd be better off letting the heart attacks happen and take the 3am on-call and be the hero instead. It would be good promo doc material, and being a hero is extremely good insurance against getting kicked out of the country (via the PIP->H1B grace period expiry mechanism).

      • mightyham

        today at 7:06 PM

        Speaking from my experience at Amazon this is not the case. Any customer impact like this would necessitate a COE (correction of errors) report, which means a list of required action items to prevent such issues from happening again, which typically suck up at least man-month of labor. Not to mention the report itself, which has to be written by a manager.

        In fact, there are regular AWS-wide meetings where L10 technical staff will randomly pick and review reports from across the organization. Getting picked for one of these is not a fun experience.

        COEs are such a huge annoyance for teams that they create a strong incentive to be proactive in preventing issues like this from happening. One of the rules when it comes to writing COEs is that they are not the fault of individuals but processes; but in reality, no one wants to be the cause of one.

        • eventualcomp

          Amazon is heterogeneous. So much so, that positive anecdotes and negative anecdotes are near worthless without specifying the org.

          Depending on if you're a cost cutting team, fixed expense team or organization, if you're a revenue driving team, or if you're a core team, or the very many other splits you can come up about the relationship between the expense/balance sheets and the team itself...there are very very different attitudes towards COEs and leadership principles.

        • awakeasleep

          today at 9:07 PM

          Having been the manager writing those reports, you can only practically find causes that are within a single team’s ability to resolve.

          If you find a problem like this thread’s hypothetical, the process stops being an annoyance just to line level managers, and something that directors and vice presidents need to handle by changing strategic priorities within their organizations.

          That entails a real loss of face for them, and because they are the ones who actually run the show, it would will only happen if you have one that is naïve or a masochist. In either case that moves them out of management.

      While I didn't work on AWS, I did intern on the retail side of Amazon, and there's definitely this sort of monitoring in place. Surely somebody was paged. And even if not, this is "just" the cost explorer estimations, not what is ending up on folk's bills.

      I learned about <https://en.wikipedia.org/wiki/2011_T%C5%8Dhoku_earthquake_an...> from alarms like this, as sales in Japan almost entirely stopped.

      I've been told a tale of another incident where some customer ran some huge cpu-intensive workload that didn't do any networking. It caused various alarms to fire because it "looked like" a part of the network was idle (potentially indicating some sort of networking failure)

      It's generally (in the broad sense) easy to add alarms for things going wrong, but in my experience anomaly detectors are just as likely to fire from other weird things like that happening.

        why would a test setting unit to Bytes fail and not MB, KB, or GB, and so on? That's like trying create a unit test for email opt-in, both true and false are valid values. It's up to the user to select the right one.

        • 27183

          today at 8:22 PM

          I'm not quite following your objection.. I'd expect a test that checks the multiplier is correct would detect orders of magnitude discrepancy. So if you're billing $x/byte you'd write a test for the billing thing that checks that, given y bytes, the bill is x*y.

          [edit] This may need to be an integration test to be effective, there is a certain peril to mocking that could bite you here. But that's fine, we have the technology.

  I wonder if AWS billing still uses CSV files for passing data around.

  IIRC it was one of my first on-calls at AWS over a decade ago now, and I got a page early evening because some stuff we did with billing records broke because some "smart" engineer thought it'd be a great idea to put an experimental record in with a description something like "I wonder what happens if I put, a comma in this field", into the production record. I watched region after region fail the same way as the record spread. That one engineer made a mess of lots of people's evenings. They could have used the test endpoint, but no. Much better to test in production!

  • anvuong

    today at 8:42 PM

    That was just a massive operational failure, not the fault of any single engineer. No change, except hotfixes, should be able to land on prod unless it has at least go through test, staging, and at the scale of Amazon, shadow testing.

    Engineers will do what engineers will always want to do, they want to see how things break, and sometimes they manage to fix it.

      I’m not so sure about that. I can see a real rationale for creating sanity checks using AI to more quickly/proactively catch pathological billing issues before they become HN nightmare stories. They wouldn’t replace billing code, but there are many ways that stupid customer mistakes can cause real costs to Amazon that either have to be refunded and absorbed by Amazon or paid by the customer causing a negative opinion of AWS. If a billing AI watching costs in realtime could detect, say, a lambda loop in the first 10 min and either alert the customer or kill it, that would make AWS feel a lot safer to use. Enumerating these conditions and fixing them individually is a task that Amazon has proven incapable of achieving. An AI watchdog layer might be the perfect shortcut to addressing all of these problems at once. Because it’s well-trodden territory that AWS has so many multi-thousand dollar foot guns that make it really scary to use as a hobbyist or small business on a tight budget.

      • skywhopper

        today at 8:23 PM

        This is exactly the sort of thing that’s not possible, though. An AI will not be able to detect a “lambda loop” because it will look exactly like a “successful lambda rollout”. This sort of watchdog would just as likely shut down the wrong things and make AWS feel a lot less safe.

    • londons_explore

      today at 4:55 PM

      Probably not actually. Transferring one kilobyte across a network link has such a low value that the billing costs of aggregating it cost more than the revenue.

      So instead you take a probabilistic approach - charge the user for a megabyte of data transfer 0.1% of the time, and bill nothing 99.9% of the time.

      Now the typical cost is the same, the users bill is probably accurate to the cent, but you have divided the number of billing records by 1000.

        In order to successfully sue for emotional damages, you have to prove quantifiable damages. Usually that means if you ended up having to get therapy to deal with it, you can sue for the cost of the therapy.

  Time to get a second job buddy.

It's crazy enough this will be fixed soon.

Years ago I found an actual hidden error in my bill. (This was early 2010s). The system was calculating the EC2 reservation savings incorrectly for some of my servers. I was crunching all their detailed usage data on a regular basis in an 18 tab spreadsheet and couldn't get it to fully reconcile. I spent months trying to track down the discrepancy. Once I found it, I had to convince AWS their system was wrong, which took another big chunk of time. Meanwhile the discrepancy continued to accumulate.

After 14 months I got a $7,000 refund. I was told it had to be approved by the head of AWS. I've never seen a calculation error on their part since.

  $7,000 of credits is no problem. At that time a friendly neighborhood PM or director could issue the credit without much oversight.

  Your problem is the time period. Amending a bill in the same cycle is EZ. Fixing the previous cycle is a PITA but pretty common. Issuing amendments for the previous financial _years_ would be a huuuuge PITA going through finance etc.

      There's a certain obligation on both sides of a contract to pay attention.

      If you're not watching your billing, and then try to claim overcharging a year later, you'll get a lot less satisfaction even from regulators or judges than if you notice it when (or soon after) it happens.

      • michaelmrose

        today at 7:01 PM

        Cable bills are extremely complicated on purpose and people are taxed for time attention and intelligence.

        The employees and company have an obligation not to exploit this even if the issue is only discovered after the fact.

        You don't get to export any of the responsibility to your customer. They don't prepare the bill and it's not their job to find your fuck ups

    I've personally noticed and saved multiple $xx,xxx monthly cost billing spikes just by take a daily glance at our cost explorer. I'm in the AWS accounts every day doing investigative work anyway that an extra 30-60 seconds is trivial.

    Seeing something "small" like an ECS task that is continuously failing to start properly because of a bug and repeatedly pulls a container image or a lambda function that's taking longer that it reasonably should (takes 5-10 seconds when it's normally a tens or a few hundred milliseconds) can dramatically drive up a bill in short order.

  The user is asking me to calculate how much money they should charge their customer. The values they've given me are 0.45, 1.67, and 2.50. This is 2.50 + 1.67 + 0.45 = 4.62, but it could be any other number. Perhaps we should be concatenating the numbers instead. Wait! The . could also mean multiplication. 0 . 45 . 1. 67 . 2 . 50 = 3015000. But wouldn't multiplying by 0 zero it out? That can't be right, we wouldn't be charging anything. So 3015000 must be correct.

  I went through a two month long fight with AWS over a compromised account. I lost 20K even when my previous usage for the last 3 years was like $20/month, and I had more invoices coming worth tens of thousands of dollars. AWS refused to help until I stopped the breach myself, which required me to spend several all nighters after work learning how to script for AWS infra. They also refused to close my account after the breach was under control. They asked me to sign a shared responsibility agreement before they could look at my case, which I refused to do. I finally contacted the AG office in my state and they email AWS directly. In less than 24h I had a AWS manager calling me to fix my account and issue a refund for the 20K. Still, they refused to close my account after all this ordeal, apparently there’s no way for you to completely get out of AWS once you are in. It’s the shittiest business ever.

  • largbae

    I had a similar situation where some dormant account was still charging my credit card.

    The account was probably real, made for some purpose 15 years ago. I had ignored the charge for years because it was like $7 a month. Then it went to $300/month, making it worth the time. I could find no invoice email and none of my AWS accounts lined up with the bill.

    I tried contacting support, but without the account number involved they had no way to help. I disputed the charge, the bank refunded that month and then went right back to charging the next month(my credit card helpfully accepted the charges despite the dispute).

    I had to cancel the credit card entirely to make it stop.

        I still have the account cancellation confirmation e-mail from Amazon Pharmacy, but Amazon won't close my account. Amazon's account rep says it cannot close accounts for "legal reasons." Bullshit. He can't say what the legal reasons are, or point me to a document stating these conditions.

  I saw this in action on a smaller scale. In a past job, my wife organized events for a decent sized company. After an event, she'd typically have a $300k+ balance on her corporate Amex. When she went on maternity leave, the person filling in for her job neglected to actually pay the bills, so when she returned there were quite a few emails and voicemails from Amex regarding the over $500k balance.

  The messages started as polite and eventually started to get more desperate in tone. At no point were they threatening or adversarial.

  • Imustaskforhelp

    today at 3:23 PM

    I think that this might reflect more on Amex to be honest.

    Amex realises that threatening would hurt their business trust more than anything. During the great depression, Amex accepted checks from other banks which were falling and paying through their own wallet as a matter of integrity. Amex has always been built around this idea of trust and prestige.

    They make most of money from what I have heard on the transaction fees which are more than others (3% compared to 1%). They might get desperate but I am sure that they are one of the last guys who would wanna threaten you if you are paying some large bills for them (as compared to normal credit card companies which might even hire people to extract your loans in some messy situations)

    So perhaps be so rich that the credit card company understands it as well and treats ya differently :-D

    • xp84

      today at 3:39 PM

      Interesting. And hard to square with my perception of banks as completely mercenary and ruthless. I had a decade-long personal boycott (I know, LOL) of Amex after they, because, with otherwise perfect credit, I forgot about a $30 department-store card bill and got a 30-day-late mark on my report, Amex got spooked and abruptly closed both my never-late accounts with them (which were at or close to 0 balances). This was around 2008 though, so perhaps this was a genius algorithm designed to try and detect the very first whiff of consumer defaults, so they assumed that $30 was the first domino to fall of my personal financial ruin that could lead to me charging my accounts to the max and then going bankrupt.

      (I eventually admitted to myself that Amex isn't a person and thus not really capable of insulting my honor, but it took a while!)

      • Imustaskforhelp

        today at 6:08 PM

        Most banks are completely mercenary and ruthless unless its in their incentives to other outcomes. Incentives lead to outcomes and mostly AMEX's incentives are in being the most trustworthy because their real targets are mostly billionaires/heavily influential people.

        This does feel a bit silly for amex to do from what I've heard. Probably 2008 were a weird time in general where trust in systems itself were mostly eroded, whether of people to banking institutions and also vice versa.

  That sounds bad.

I realized recently that Whole Foods no longer automatically and reliably detects your Chase Amazon Prime credit card when paying. So they don’t give you the discounted pricing automatically. I wonder how many customers are checking out the way they always do and are paying full price when, for years and decades, this worked fine.

The customer service people I talked to in the grocery store said this changed sometime in the last year. My guess is that it’s an unintended side effect of removing the pay-by-palm feature.

This is obviously unrelated but I joked about what else Amazon wasn’t reliably calculating….

  • xp84

    today at 3:31 PM

    Relevant to this, I've recently noticed a trend of mass tort cases being opened up in the past couple years, and they seem to do very well. The way these seem to work is attorneys identify a company who has clearly ripped people off, and what I presume is a repeatable way to guarantee a win (thus translating to a guaranteed settlement offer). Then they advertise for eligible clients, sign those clients individually to contingency agreements, and run the playbook. A couple months ago after signing up for one of these, I received a check for about $350 (after the agreed-upon 40% attorney fee), from Ticketmaster, and I had another one related to AT&T. It took about 10 minutes more effort from me than a typical class-action settlement, because I had to e-sign those representation papers.

    So really, there's a third option now, that's much easier than class action, even when class actions don't get certified.

    Weirder is what happened a day later. I got an email that said my Chase Amazon Prime credit card was being re-associated with my Amazon.com account.

    I never reported this nor took it up with either Amazon or Chase directly. There was a refund of my Whole Foods purchase (they needed to void my purchase and re-ring everything to give me the discounts.. I asked them to refund my purchase and I’d do without my Whole Foods purchase entirely).

    Looking back I think at least 3 recent visits were charged to me at full price because of all this. Hard not to think of enshittification and whether Amazon Prime is even worth it, alas.. I live in a fairly rural area at the moment and need delivery.

I got a 20K bill once and it was actually drafted from my bank account. It took me a couple of months and involving the office of the AG of my state to get the issue resolved and get my money back. Since then I never touched any AWS product, moved my small stuff to Azure. It’s been years since AWS have these issues with billing, you can find the stories online, students billed 60K for a compromised account launching servers to mine crypto which AWS somehow was unable to flag and block, and let run for months.

  For a while I had a portion of my "homelab" on AWS. I was an educator in a classroom where the students were learning cloud stuff, and the instructor was encouraging the students to stand-up cloud environments for learning, so I figured that I would do the same.

  I used AWS' free tier, of course, and I enjoyed the initial setup in EC2, and I did a LAMP-stack MediaWiki installation. It wasn't too difficult, but two things sent me away forever.

  1. It was impossible, or at least highly labor-intensive, in this modern era to adequately secure an ordinary Linux system running Internet-facing services. I put fail2ban and I filtered a lot of ports, and still spammers attacked me on Layer 7.

  2. It was impossible, actually impossible, to limit or cap my cloud expenses in any billing cycle. Sure, run free-tier all I want. Sure, come in within the limits almost every month. But if I configured one thing wrong, or one thing went runaway, I'd have a sizable bill that I couldn't dispute. And even worse, those "runaways" weren't necessarily things in my sphere of control, but could be triggered by basically anyone coming in and using my VPC resources, especially egress network traffic.

  So I closed out my cloud account, and I developed a lot of sympathy for businesses and corps that now are forced to run "in the cloud" rather than on-prem or their own machine rooms, but now they have no way to control expenses.

  Right, and good luck getting a correct bill from Azure. And when you are finally fed up, it will take months to close your Azure account.

Probably the closest I've ever been to getting a heart attack. Normally <$1 per month, and now suddenly $284,006,266,443.74. Whatever the bug is on their end, this is unforgivable.

• everforward

  today at 3:07 PM

  Yeah, this one is bad because it’s off by so much I’m shocked it wasn’t caught by tests, alerts about unusual changes in the billing system, or even accounting. Like surely the P&L reports look all kinds of wrong right now, they have to be showing like 6M% profit margins and revenue measured in quadrillions.

  I’m also a little surprised this didn’t trip a circuit breaker. For something as non-real-time as billing, I’m surprised they don’t have an automated kill switch that pauses the billing system and fires a page if variance in bills spikes. Naively some kind of “if the standard deviation of customer bills for this year changes by more than 50%, pause the billing system”. At that number of customers, those numbers should be pretty stable beyond internal billing changes they could normalize for.

  • TrickyRick

    today at 3:54 PM

    If I were to guess this bug is in the "display" part of the system which is probably distinct from the "actually take money from the customer" part of the system. One can imagine they have gates on the "actually take money" part, especially for a large bill like ours which was ~$300b or about 2.5x AWS' 2025 revenue... In one month. Surely if we had actually accumulated that bill they would be the ones with the problems when we can't pay it.

  Somehow I highly doubt anyone will leave AWS over this unless their use of AWS is way more low-complexity than the average account.

  People make similar pronouncements after every us-east-1 outage makes the news, but I feel like AWS would be going out of business by now if people followed through.

  It reminds me of airlines, where after a particularly grueling irregular ops experience, a few dozen people file off the plane swearing "Never again, <airline name>!" but really, we all must know deep down that the airlines are all subject to the same external inciting factors, internal profit motivations, and human imperfection, and thus all pretty equally likely to cause us a bad day or ruined trip. The effort spent to avoid one isn't really worth it.

  Clearing LLMs out of our business infrastructure is going to be a massive undertaking. Though I have a tech background, I work in commercial real estate. We are recently seeing new levels of idiocy from the employees, including real estate brokers with zero tech knowledge "coding" solutions to find sites for clients and blindly trusting the output (which I came to find out was complete bullshit), as well as some who have literally stopped communicating with any of their own language - meaning every interaction they have with anyone not in person is made by an LLM. It's a massive threat to our brand and has got to stop. I can't imagine what companies with thousands or tens of thousands of employees who have really been riding the LLM train are going to have to deal with.

    Well then hopefully next time they'll be a bit more careful when shipping billing code updates!

As someone who usually works with data analysis, the distribution of the numbers strikes me as odd. Almost all of them have one number that appears four times, and one or two that appear three times. And overall, there are an unusually small number (0–9) of digits that appear at all.

Maybe it's not just vibe-coded, maybe the numbers themselves are being hallucinated by an LLM.

• berkes

  today at 3:01 PM

  > Almost all of them have one number that appears four times, and one or two that appear three times

  To me that looked suspiciously like string-handling in a weakly typed language.

  Like when you do `"100" + 1` in JavaScript, or `int("100" * 2)` in Python.

  I've seen my share of such bugs in PHP, Python, Ruby, JavaScript. In production. Obviously not as simple as the examples, but subtle, like when a library update changed `someFancyLocalStorage.getOrDefault("lastOrder", 100)` by always casting the value to the type of the default (released as patch release). Or where typedEnvGet() should typecast "numbers", but keeps it a string when theres whitespace `AMOUNT_PER_CALL=100\n`. Or where a number passes through a deep stack of middleware and 99.9% of the times remains an int but in rare race conditions becomes a string. etc.

  No evidence that's the case here. But from my experience, the repeating and strange formats of numbers hint strongly in that direction.

  • galonk

    today at 3:56 PM

    Pedantic as hell but `"100" * 2` in Python (= `"100100"` for those who don't know) isn't really typing, it's operator overloading. Any language with that could implement the same questionable design decision.

    • Sohcahtoa82

      today at 7:06 PM

      And as much as I love Python, being able to multiple a string by an integer doesn't make sense when adding an integer to a string is a TypeError.

      Being able to repeat a string is fine, but it should be a str.repeat() function, not an operator overload like that.

Has anyone received any proactive communication about this? I didn't see the email until about 9 hours after it was sent out, yet I still needed to seek out information as to a) whether this was real or phishing and b) whether the amount was correct.

Seems totally irresponsible not to send an immediate follow up email to make customers aware.

Cynically I wonder if this has an outcome as an unintentional (or intentional) anchoring exercise for future cost increases

  Can you not set spending limits in AWS?

  • inigyou

    today at 11:52 AM

    No you can't. Spending limits imply realtime billing backend flows and they also imply deleting all your data so that you don't pay for storage.

      I heard this false justification already in 2007, in spite of many customers asking for it.

      Incidentaly, smaller competitors solved this issue decades ago, while the big cloud decided it is more convenient never to implement it.

      Realtime billing seems entirely within the abilities of AWS.

      "Limits except for Storage" seems even easier - I don't think I've ever heard of a storage-based billing story, although I'm sure one or two exist

      • everforward

        today at 3:15 PM

        Storage-based billing is huge, unless you mean something other than “places that make you pay for storage separately”.

        Also many places I’ve worked, storage is a huge part of the spend but that depends a lot on what you do. e-commerce doesn’t use a ton of it, but if you handle user-generated content or do any kind of training (LLM, computer vision, etc) then you can very much end up in a place where storage becomes a top line number for infra spend.

        GitHub pre-Copilot was probably like that. They host a shitload of data, most of which is just at rest the majority of the time. Storage and networking are probably the majority of their infra costs.

        • inigyou

          today at 4:18 PM

          Storage-based billing stories. When an account is hijacked it's always for compute, not storage.

          • everforward

            today at 4:53 PM

            Oh, I also don’t think I’ve ever seen that but I’m not surprised. Even if you could steal a huge amount of storage, filling it with data would take ages and the cat and mouse game of moving the data as hacks get uncovered would be untenable.

            I have seen things get hacked for bandwidth, back in the days before you could rent a gbps uplink from the cloud for $0.12. Some scene release groups would hack into universities or companies to do the initial seeding over their super fast links. It used storage, but that wasn’t really the goal.

      > and they also imply deleting all your data so that you don't pay for storage.

      Not necessarily. They could imply that your storage becomes inaccessible immediately, but only gets deleted after some time period (say, 1 month). What spending limits do depends on the implementation.

      • inigyou

        today at 4:17 PM

        That's even more work to implement. And now you store files on a second account that pays for only one day a month to not get deleted.

Several comments here talk about "nearly" having a heart attack. But I wonder: since it's happened to so many people, chances are someone had a heart attack for real. Can they legally be made responsible for that?

• justusthane

  When someone says "I nearly had a heart attack," it's _highly_ unlikely that they actually nearly had a heart attack. I don't think the chances are good that anyone actually had a heart attack.

  • tanseydavid

    today at 4:05 PM

    While I agree that this phrase is most commonly spoken in a figurative sense, folks with marginal heart health have a much greater than 0% chance of having something of this nature trigger an actual heart attack.

Someone I know woke up this morning to over 3 trillion dollars.

Love to see how hyperscalers make your life easier and less worrying.

Question: Why does AWS need to roll back estimated bills to a "last known good" state? I get wanting to do that for ACTUAL billing mistakes, but for estimates, they're just that -- approximations. I guess it's fine for predictive purposes to store estimates so they can be compared to actual usage and optimized. But why would AWS bind the values of present estimates to the estimates made earlier in the month. The calculation should always be:

1. Current month's usage * applicable rates; + 2. Estimated future usage for the month * applicable rates.

And Item 1 obviously requires proper data persistence, but Item 2 is just a projection. If they don't have Item 1 correct, AWS's whole system is in question, but I don't think that's the issue. I'm going to guess now -- looking forward to reading the root cause analysis -- that the problem is that someone decided to get too fancy with the estimates, and built a latent requirement that all prior estimates for the month must be available to compute the current estimate. Without estimates working, no estimates are available, and some denominator in an averaging or smoothing or normalizing function goes to 0; then everyone's estimated bill explodes without bound (subject to floating-point arithmetic) resulting in trillion-dollar estimates.

• donavanm

  today at 5:17 PM

  Thats not really how estimates work. The actual metering data is ingested in near real time. The metering * pricing plan is processed within a few hours; thats what youre seeing for “estimated spend” IIRC. The actual billing accumulation is done later, at the end of the cycle, because pricing has cross service discounts, price tranches, credits tied to total spend, etc.

  “Rolling back” estimated bills is reprocessing the historic metering data by an older or newer pricing plan version. As i mentioned in another comment someone will have messed up a metering type vale (eg GB/B). Thats why theyll need a few hours to redrive the metering data.

I feel much better after seeing the $B estimates here; I only have an estimate of $34M so far

I wonder what's going on; they still don't have a potential solution after 7 hours and they have multiple teams on it. Never seen anything quite like this

I have just received a similar alert for $ 5b

AWS on their support data is reporting this:

Inaccurate Estimated Billing Data

Jul 17 3:03 AM PDT We continue to work to resolve the issue affecting estimated cost and usage data displayed in the Billing and Cost Management Console. We have identified the root cause as an issue with unit pricing within the estimated billing computation subsystem and we are working on a mitigation. The displayed billing estimates do not reflect actual usage and charges. There are no customer actions required at this time. Once the issue has been mitigated, we expect full resolution to take multiple hours as we work through recomputing the estimated billing data. We will provide another update by 4:00 AM PDT or sooner if more information becomes available.

Jul 17 2:07 AM PDT Beginning on July 16 7:38 PM PDT, we began displaying incorrect estimated billing data in the Billing and Cost Management Console. Our engineering teams are engaged and investigating root cause. We will provide another update by 3:00 AM PDT or sooner if more information becomes available.

Jul 17 1:33 AM PDT We are investigating issues with Cost Explorer reflecting inaccurate estimated billing data.

Ditto on the heart attack. My cost estimate for the month is currently $223,509,270,216.17. My girlfriend suggested contacting Elon for help. Glad I found this thread. Maybe I should create new keys anyway, this stuff freaks me out.

Looks like they set up a LLM to estimate billing?

I've had a mysterious Neptune cluster appear on my billing. Never used it, no API key access (or IAM instance profile access, OIDC etc), nothing in my console shows I've ever had one in any region. Raised a case with support, they ignored it.

Maybe it’s one of those absurd situations where canceling a service doesn’t actually stop the charges. Instead, they quietly begin billing you for some random add-on that was bundled with the original service. You never knew it existed, never knew it had to be canceled separately, and now you’re paying full price for a completely pointless ghost service because the only thing it was tied to has already been canceled.

It sounds ridiculous, but something very similar happened to me with Amazon WorkSpaces. During the WorkSpaces setup, an AWS Active Directory (Directory Service) instance was provisioned as part of the deployment. When I later canceled WorkSpaces, I had no idea the Directory Service had to be deleted separately. I kept getting billed for it, and it ultimately cost more per month than the WorkSpace itself had.

Tale as old as time. When I was coming up it took a $20-40/m investment to get a "dedicated" server that you could start tinkering around on. When you couldn't afford that, you bricked the family PC trying to figure out how to configure your own LAMP stack.

Nowadays you just have to risk accidentally billing your parents CC the tune of multi-generation wealth to get that real-world experience.

• Imustaskforhelp

  today at 9:18 PM

  No not really, nobody has to be using AWS itself per se to be honest, there are still alternatives around.

  I mean I own a 7$/yr vps that I pay with crypto and my stack usually involves golang/rust and oh I also self host my mail for temp-mail esque things on that server and I have some other servers floating around as well.

  Its just that everyone uses AWS which is the wrong issue here to be honest. If you ask me, aside from the ram pricing caused by AI inflation, things are pretty good. The issue is that not many people know about server providers and other things and default to AWS/Azure etc. because big companies and small companies alike are using them.

Yes, I've got an estimated bill of $4bn. Probably related to the ongoing "Inaccurate Estimated Billing Data" incident?

https://health.aws.amazon.com/health/status

I generally think AWS is better than GCP and azure, but them not allowing spending caps is a big worry source for me and something that has made me pause and rethink using them. A bad click or a bad actor can create tens of thousands of dollars of spend nearly instantly and they can, and will, bill you for it. I can understand that stopping services is hard but some system would be good. For instance, if they had a two tier system where you could stop new services and active things like EC2 would shut down (but not delete) if spend is > x, that kind of thing. Some sort of 'stop the bleeding' concept would give me a lot of piece of mind using them.

I was actually in the toilet when I got an email I owe them $36,869,876,146.51. I literally just shit myself.

logged in this morning to find a bill of $595 Billion... heart rate went through the roof... then I noticed the open issue, phew! nice one guys... you got me there...

But with AWS costs rising anyway (not by that much but OK), I'm probably not the only one to start reconsidering their cloud strategy. I think this might have just pushed me over the edge.

  Even if it was 595 billion, that sounds like their problem.

  "If you owe your bank manager a thousand pounds, you are at his mercy. If you owe him a million pounds, he is at yours."

AWS pushed the wishful thinking internal calculator to production.

It would not make sense for even a 1200 baud dial-up BBS from 1985 to charge by the byte.

In 2026, the gigabyte should probably be the default/minimum unit for something like AWS.

""" If you own the bank $1000, thats your problem.

What I would be curious about (and I'm sure AWS will never share) is where the incorrect number came from. If the number is somewhat consistent between some groups of accounts, my first guess would be they started summarizing billing across all accounts in whatever cell/grouping/heirarchy AWS architected internally.

Which is just funny.

My guess is that it's because of some vibe-coding stuff! We are using LLMs to write code, validate code and test the code ! What can go wrong ?

Given the wild but apparently "consistent" numbers I wonder if we could reverse-engineer the wrong algorithm with enough data points? Maybe the proper cost estimate has some relationship to the reported cost estimate.

Are you sure it’s a bug ?

The crypto network you hosted should pay for itself in 10-20 years just like LLMs. Don’t worry. Consider Bank of America until then if you are good on credit score.

It's a good job it was off by such a large amount, or I might have panicked instead of writing it off as a phishing attempt. I had an email saying my $7.50 budget had been exceeded with an actual cost of $3bn.

In moments like these I'm reminded of all the people who have committed suicide due to billing errors. This is completely unacceptable. These sorts of errors must _never_ happen.

It's okay. They are market leaders. And we use their services cause we can trust that they know what they are doing.

For anything below a Trillion, you should just take it out petty-cash. </sarc>

My sympathies -- I know I would be overcome with panic in such a situation.

My first thought was "Oh hell, who left the NAT Gateway on?"

I am running a niche SaaS with around 20 users per day on AWS.

I too was shocked when I saw the $1.7billion bill, instead of the usual $1.5billion.

Who is going to compensate us for the years taken off our lives when we received the alerts?

Only 1.7? I got $55B up from 41 cents.

I literally almost had a heart attack today.

Funny how these errors always go one direction.

Will wait for the RCA, the update says that they will resort to last known estimate as of 15 July. I’m guessing that would imply that the bug is at a lower level, write or an ingestion path.

Mines was $190,594,974,587,761.20 :)

Wow. As a side effect, this outage is handing Corey Quinn material for the next 4 years of AWS shitposting. No longer is NAT Gateway the prime target.

  $28m actually seems worse. If I wake to a $100b bill, that’s obviously a mistake. If I wake up to a bill in the millions then my first thought would be “oh no what did I do wrong, this will ruin my life”

yeah.. i just to a daily cost alert.. it was only 23 trillion dollars this month. i thought, hmm seems kind of high this month.

The new data centers are more expensive:

ACTUAL Amount: $1,046,294,123,330.95

The market *hates* this one weird trick to juice earnings

Looks like you are the biggest shareholder. Well, going by the popular saying: “You own AWS now”.

It looks like AI is completely done.

Our org account's bill is showing up as > 100 trillion.

Nothing like generational debt to kick off a Friday morning

  This is generational debt for a Kardashev Type III civilization. If there are individuals who are being charged "the whole of the GDP the human race has ever produced", then Amazon is claiming the rest of the world owes them a fairly significant portion of the galaxy if you consider the entire billing claims being made here.

  There have been some big billing errors in the past but I wouldn't be surprised this is a new record, by some orders of magnitude. I know I've seen people charged around 92 quadrillion, which is a rounding error from underflowing a signed 64-bit integer with pennies, but those stories are usually isolated individuals. It sounds like the aggregate error here may comfortably exceed that. Hard to tell how widespread this is; as a data point my ~$2.00/month spend on S3 seems to still be billing correctly, so it must not be affecting everyone. But a few trillion here and a few trillion there and you get up to those quadrillions pretty quick.

it seems like these types of problems have gained frequency in the ai era, or is it just recency bias?

Some guy named Claude screwed up.

I had Hermes managing mine, and it made a partial prepayment to help smooth out the bump in my account balance. Unfortunately Billing Support say my $17.4B refund may take up to 10 calendar days to be processed.

To be exactly that guy:

This cannot happen if you do not do this renting at variable rates.

A thing you own doesn't suddenly bill you trillions of dollars in error. It doesn't hyperscale either, but neither do you.

Have even seen a $9.2 trillion for a friend.

Did it recover for you folks? I still see billions of dollars!

I prefer to just pay...

Amazon, the first quadrillion-dollar company.

Just got a call from the IMF president begging me to not default my debt with Amazon and offering me credit line and a plan to re-structure my debt so I don't create a global financial crisis with my default.

Just got mine. $534,366,582,647.75

  Shocking! That seventy five cents is suspicious.

yeah the AI read billionaring instead of billing

Vibe coded fix, resulted in many having multi billion bills. Claude really did it this time.

vibe coding for the win.

Yes seeing the same, so far no response from AWS support

VibeBilling, love it

I expect such incidents like this to continue. So please keep vibe coding.

I almost had a heart attack because of this. I was like, did I mess up my API management? Why didn't I just use Lightsail? Those were the thoughts running through my head.

My personal website is on Lightsail, but those alerts started popping up from some test services I had set up while I was studying AI. I swear my heart nearly stopped and I cried. I really think AWS should have spending limits in place.

My bank account barely has enough for next month's rent.

This generation is too entitled! He should some learn responsibility by paying the full amount; otherwise Amazon should delete his services/data. Consequences!

Curious if it's just s3 costs or other services as well?

• jatin_oo71

do you see cost ever day for the month of July or just the last day? I also have billions of dollars in cost explorer

  now it is fixed for me as well. issue is still open in aws health center though

Yea, same here. $420M+ bill, when we have <10$ per month usually.

$627,487,837,871.49

I might be a winner.

The charge-back penalties are going to be hilarious and hopefully bankrupting.

  A lot.

Thanks for sharing.

I’m currently dealing with Verizon Wireless and their “Jabronibot” claiming I have a fictional account balance due. It has been sent to collections, but still is being asked for by their legacy system.

The case studies of “Agents in Billing Departments” and potential shareholder lawsuits / E&O claims / reputational damage will be interesting to me. I worked in “risk management” products years ago and this kind of liability is not easily dollar traded away via contract. Will accountability stick to the Decision Makers or will they try to surrogate to the Service Providers? Hmm.

I think I know how Bezos plans to pay for his Billion dollar AI costs.

In an .md file somewhere:

"NEVER represent currency with floating point, multiply by 100 and store in an int before doing any math"

Yes I received an 2.8m USD budget alert.

I just invested ALL my money into AMZN cause next earnings report will be FIRE :)

Results of vibe coding and vibe configurations.

File a GDPR request to have your account deleted.

Then flee the country just to be sure.

Imagine the chaos if, as people sometimes suggest should happen, AWS shut down running instances in accounts that exceeded a billing threshold..

Obvs have created an urgent AWS support ticket.

I think I would have just waited to see what happened when AWS tried to hit my credit card for $1,700,000,000.

When do you ever get that opportunity?

131 billion for me

My personal photo backup S3 account, with a budget limit of $10, now going to cost me ....

$1,299,988,247,332.56!

That was a fun set of emails to wake up to, figured they had to be phishing for how outrageous of a number it was. But nope! Fun little incident they've got going over there.

So long as customers are good for it, AWS is about to crush earnings!

Mine was a mere $49B. Fucking idiots.

If its less than 2 billion is likely to be real :-) I would relax only if its in the trillions ...

AMZN Q2 numbers are in, and it turns out they're going to Goldman Sachs the AI bubble.

I guess on the plus side I'm $1.7B better off so I can retire...

Is AWS in their "move fast and break things" era ?

• jagged-chisel

  today at 2:25 PM

  Lumber along and smash stuff

AWS has become the uber employer: before AWS, you just had regular employers steeling employee wages bit by bit by forcing work, skipping breaks, etc.

All hail the new generations of our uberployers.

Same, i am now a slave to Jeff Bezos to the end of my life.

Three billion dollars sounds about right for a free week of Kiro in the default Agentic mode. We usually see slightly higher numbers, so I wouldn’t be too concerned.

storage, compute cost is increasing AWS be like lets increase prices

Imagine it not being a bug...

I got estimated costs of $56.something billions. Usually ~$100/month. My heart rate currently still sits at around 160 bpm. Motherfuckers.

you too with Fable huh?

invoicemaxxing

You really should get your spending under control. Unfortunately unless you become one of the real people class through a large lottery, it sounds like you owe the rest of your life to AWS until you can pay off your debts for being so careless.

aws becoming first quadrillion dollars company

someones been dognfooding the AI too muxh

I mean 3 billion USD is clearly too big to fail, so I wouldn't worry too much

did it recover for you? I still see billions

    thx, when? Was it only last day or the whole month of July was inflated?

Fast and loose with billing data. Welcome to the new Amazon.

a billion here, a billion there, sooner or later it adds up

Literal basic fucking math, Amazon.

You don't need hours to recalculate billing. You need to go back to basic algebra.

Anyone using Amazon and dealing with this should be moving away from their services because something this basic going wrong means the correct people are not at the helm of the ship.

    This is probably going to push me to completely close a couple of AWS accounts I setup when doing training courses so I could get certified (mandatory requirement from my work).

    I'm not currently running anything and have no plans to at the moment. I've always had a mild dread that I'll suddenly get a bill for more than $0.00.

    If AWS can goof in a way that causes obviously massive bills (like today), what's to say they can't goof in more subtle ways and start charging small additional amounts that many people may not notice and just pay it.

Pff rookie numbers, mine was 375 billion.

    Of course not, domain expertise is expensive no matter what the field is, and to the big companies like Amazon the whole point of GenAI is to get rid of those pesky expensive humans and replace them with cheaper humans.

Don't worry. With so much debt banks start to treat you with respect. /S

Honestly, I would worry more about estimated billing that seems plausible in general, but is way to high for you personally. These ridiculous amounts? Not so much.

• Hamuko

  today at 10:52 AM

  I got freaked out by the mere fact that I got a billing alert, since getting one would require my monthly spend to have suddenly exploded.

Clearly they weren't tokenmaxxing hard enough or weren't using the latest models /s.

What an absolute joke. All just so that line goes up. As if their fees weren't high enough vs. alternatives (especially egress). And I'm sure the pro-AI crowd will keep saying we're luddites for not loving this clearly revolutionary and disruptive tech.

Of course, this is only considered an error if the account is unable to pay. /s
