Ask HN: Iran's 120h internet shutdown, phones back. How to stay resilient?

94 points - yesterday at 5:53 PM


It has been 120 hours (5 days) since the internet shutdown in Iran began. While international phone calls have started working again, data remains blocked.

I am looking for technical solutions to establish resilient, long-term communication channels that can bypass such shutdowns. What are the most viable options for peer-to-peer messaging, mesh networks, or satellite-based solutions that don't rely on local ISP infrastructure?

    Surprised to not see it mentioned (more) in this thread. Uses Bluetooth and can bridge via Nostr.

      States like Iran have signal catchers, where they can get a rough idea where a signal is coming from through triangulation. The US military has had this for over 20 years now. Often these coordinates are fed in as targets into weapons systems.

      If you're going the radio route these come to mind:

      Meshtastic: 1W, one band, local. Useful if Iran doesn't know about it. But easy to jam and probably triangulate.

      Wifi Halow: 1W, can possibly hop between bands, but probably also really easy to jam and triangulate.

      WSPR: Possibly good, transmitters can hide in the noise floor, and can go long distances with 100mW of power, but slow. Probably triangulable, very easy to jam once located in the spectrum. Data can be transmitted and received with off the shelf components.

      Military Radios: Very good. Transmitters can frequency hop, making triangulation and jamming difficult. Also encryption. You can easily transmit in the same frequency space that Iran would be using to avoid jamming. But also, mostly unobtanium. I have heard stories about US military radios showing up at Ham Fests.

          WSPR carries almost no payload data and by default it literally broadcasts your location. You could modify it but it will still take ages to send a short sentence which is probably the last thing you want when you want to avoid getting caught.

          Short bursty spread spectrum hopping seems to be more what the military do and they also care deeply about triangulation.

              Just to underscore this WSPR sends 50 BITs of data in 110.6 seconds - a data rate of less than 2 baud. It's not practical for really any kind of message passing. Using CW (Morse code) would be at least an order of magnitude faster.

            Not knowing much about radio hardware your post made me wonder why we don’t see too many options for radios that can do this outside the military. Is it because there’s rarely a practical use case outside of avoiding jamming? Or is the hardware to do so prohibitively expensive?

                There is actually a lot of fairly inexpensive SDR hardware aimed at amateurs, and other ways to do cheap packet radio. But outside the amateur radio community you might not hear about it because you need a license to transmit.

                  Radio spectrum is licensed, and licenses are very expensive.

                  There are several bands for Amateur radio in US/EU/AU, but it is explicitly forbidden to use any kind of encryption on them. So no one can sell devices that use encryption on those bands.

                  And I doubt Iran was friendly to amateur radio in the first place. E.g. in USSR it was crazy to think of any non-approved radio.

                      I mean who can stop you from transmitting anything you want at any frequency? Licenses etc only matter when the rule of law is a thing.

                          It's trivially easy to watch the entire radio frequency range at once and triangulate the location of any transmission. If someone more powerful than you wants to stop you, they can.

                                  It's (scarily) available in the commercial sector[1][2] from space if you have the need to purchase their services.

                                  Suffice to say, military and intelligence agencies are probably a few generations ahead of this and you won't find them commenting on strategic capabilities on HN.

                                      Thanks! Technically, what do you think is the biggest obstacle to achieve military grade hopping? Is it just cost, or something you simply cannot buy from open market AND cannot make one if you have the knowledge?

                            Once you transmitted, you’re exposed so the authority can find you sooner or later

              Old fashioned phone trees can be really useful IMHO OP. We used them when I worked in a school. If there was winter weather, you'd call say, everyone with a last name from A to G in the staff directory, someone else calls G to K, and so on and so forth.

              You can combine the phone tree with literal runners -- so basically, someone takes their burner and calls suburbs A,B,C and D and then the runners go out and pass the word about the protest or action.

                  Presumably the phones are tapped?

                  People have been claiming for years that US phone calls are subject to routine computer analysis (Echelon); these days that's a relatively cheap thing to do with LLMs.

                  I suspect the literal runners solution is what's happening, although that's also very dangerous when the police control the streets.

                  And don't forget the whatsapp group chat classic: secure communications where at least one person in the group is leaking them.

                              An important factor to consider when answering this question, is that the average monthly wage in Iran is only $200 to $500 USD/month.

                                      I guess because a single Starlink subscription would be 30-80% of their monthly income.

                                      For dense areas, mesh applications like BitChat (Jack Dorsey) could bypass the need for a network with p2p bluetooth mesh networks. And works with existing devices, vs something like meshtastic which needs an installed base (afaik).

                                          Does it actually work though? My experience with Meshtastic is it’s so difficult to get a message delivered beyond the nearest hop that it’s almost useless. And Bluetooth has a significantly shorter range than LoRa.

                                              The LoRa enthusiasts in my area seem to all have moved to Meshcore, largely because of a quirk in Meshtastic's routing algorithm that doesn't handle nodes with widely varying visibility/power/noisefloor well. They report regularly getting traffic hundreds of miles. There might be a couple mountaintop repeaters in the mesh though.

                                              For OP's situation I think runners and a store and forward system like Scuttlebutt/Briar/etc might work better. But I'd love to see a couple of thorough case studies on that kind of system, they've been around for many years targeting related scenarios.

                                                  I’ve tried MeshCore as well and discovered zero nodes. At least what I’ve seen it looks like Meshtastic implemented the same routing fixes MeshCore has.

                                                  I think the issue is more that getting a message many kilometres out using a couple of nodes sitting in non prime locations is just unreliable. The noise is too high. There’s also a limit on how many messages can be sent while using flood routing.

                                                      But did all the nodes and repeaters update to the version of meshtastic with routing? Meshcore started with routing out of the box.

                                                      I don't think it's the noise that's too high, my original understanding of the meshtastic 2.0 protocol (from this video: https://www.youtube.com/watch?v=7v6UbC5blJU) was that an edge device would receive priority. So the message might go the wrong direction, say. Or, worse, a meshtastic radio in a basement might get priority.

                                                      Because they didn't understand (or care about) network topologies from the start and reliable message transmission, not to mention the versions of devices that are still on their network, I'm guessing it's gonna be a couple more years before they finally get their act together.

                                                          I would say there are significantly more nodes on the Meshtastic network with the latest routing than there are MeshCore nodes. A gap that will likely only increase over time.

                                                          In Melbourne, Australia I was able to pick up 450 nodes on Meshtastic while I got zero on MeshCore after weeks of searching.

                                          HF radio. Highly depdendent on space weather, but generally I can communicate around the world with only 100 watts and a long wire.

                                          Be aware though that transmitting on any radio is like turning on a giant, extremely bright light bulb directly above your antenna. Anyone with basic radio know-how will be able to hear you and locate you.

                                                  It's very silly that "high frequency" is among the lowest frequencies, and that we wound up with Very, Ultra, Super, Extremely, and Tremendously High Frequencies!

                                                      It's because when the term was first used, newer electronics to generate those frequencies had only recently become available.

                                                      The HF band is 3-30 MHz. Maritime navigation was operating on 500kHz (.5MHz) for most of the 20th century because that was what Marconi's alternators used at the beginning of the system. These machines produced the carrier frequency mechanically by rotating a disc with lots of tiny magnets on it at high speed.

                                                        Back in ye olden days, HF was really high! What we'd consider today to be near useless due to limited bandwidth and insane antenna requirements were once the primary frequencies for communications.

                                                    Is it possible to setup LoRA mesh networks in Iran? LoRA chips should be on the order of <$5 bulk shippable from China

                                                    You'd have to have a huge network spanning the entire country to get a message out however

                                                        I was going to suggest LoRA.

                                                        But a country-sized network with the purpose of evading a blackout would likely have to be full mesh. A network organized into a hierarchy (aggregated routing tables) requires some coordination that could quickly be identified and squashed.

                                                        The size of such a mesh is limited by scaling factors, so this couldn't span a nation. Let's say you could do that though. The network would be completely choked up with traffic to the point of unusability.

                                                        I think starlink, satphone, maybe packet radio on small scale are the most realistic options.

                                                      Yggdrasil (mesh network) would be the longer-term solution. It is fast, resilient, and pure IPv6. But you'll have to establish IP links between interested parties to peer over. Eventually some will be able to peer over the internet, and connect everyone else to the rest of the world.

                                                          Yggdrasil was never designed to be censorship-resistant and can be blocked with trivial DPI.

                                                              That's correct. But it is designed so that it can run over PTP IP links, which is the only option in a full internet blackout. Yggdrasil is censorship-resistant in that it can form one big mesh network, without the internet or ISPs. Peering over the internet is just convenience.

                                                              If you want to peer over a censored internet connection, you should set up XRay first and peer over that.

                                                              Yggdrasil is not a darknet or anti-censorship tool for the internet. It's an alternative to the internet.

                                                                Couriers and USB flash drives can be pretty effective. They're high latency but can be very high bandwidth. Look at the El Paquete network in Cuba[0] as inspiration. Self-contained HTML/JavaScript SPAs can provide navigation and the likes of TiddlyWiki[1] can allow for collaboration. A network of couriers can move as fast as road traffic and distribute stuff pretty widely.

                                                                Contents can be re-shared locally over ad-hoc or mesh WiFi networks even without Internet access.

                                                                Encryption and steganography can obscure the contents of drives from casual inspection. You can stuff a lot of extraneous data in Office XML documents that are just zip files and look innocuous when opened.

                                                                1. For current events content add descriptions, locations, and timestamps to everything. The recipients need that context.

                                                                2. Even unencrypted files can be verified with cryptographic signatures. These can be distributed on separate channels including Bluetooth file transfers.

                                                                3. Include offline installers for browsers like Dillo or Firefox. Favor plain text formats where possible. FAT32 has the broadest support in terms of file system for the flash drives. Batch, PowerShell, and bash scripts can also be effective in doing more complex things while not needing local installation or invasive installations on people's computers.

                                                                    Do we need to come up with more internet protocols/services that don't require a negotiation process? So that it would work better with very high latency sneaker-net flash-drive networks? Especially for the already asynchronous ones like email? I could envision a user with a messenger/email-like client who "sends" (encrypted) messages that get put on a flash drive. This is carried around the neighborhood, etc, where others do the same. Eventually someone takes it to a machine with regular internet access, where the messages get delivered to their intended recipients. And then replies to these messages (coming hours, days, weeks later) also get put on a flash drive, and maybe hopefully get back to the original receivers. And if the internet-down situation has been resolved, the recipients will already have their messages, but if not, they'll get them when the flash drive arrives.

                                                                    I suppose this isn't complete without mentioning RFC 1149 (IP Datagrams on Avian Carriers).

                                                                              If you have a phone or cellular dongle with a serial interface you might be able to initiate a “data” call which gives you a modem-like link at speeds much higher than running an actual modem on the audio path. Note that this kind of non-standard usage will stand out like a sore thumb so might not be advisable.

                                                                          • mosajjal

                                                                                                  Amateur radio transmissions are public, unencrypted, and attributable. Callsigns are required, modes and frequencies are well known, and transmissions are trivially direction-findable. In a country like Iran, where RF spectrum is actively monitored and unauthorized communications are treated as a security issue, transmitting on amateur bands is effectively broadcasting your location and intent. Direction finding is routine, fast, and does not require exotic equipment. One transmission can be enough.

                                                                                                  In the US and most other countries, amateur radio is tightly regulated. Encryption to obscure content is explicitly prohibited. Ignoring this can result in fines, seizure of equipment, and loss of license. Foreign operators encouraging or participating in such use are not insulated from consequences simply because the target country is authoritarian.

                                                                                                  I did not claim to have a better solution. That's the point. When the threat model includes surveillance, attribution, and enforcement, there may be no safe civilian workaround. Suggesting amateur radio in this context is not “imperfect but helpful”, it reflects a fundamental misunderstanding of what amateur radio actually is and how it is regulated.

                                                                                                  Amateur radio can't provide privacy, safety, or reliable information flow under an active crackdown. Pretending otherwise is irresponsible.
