Terrible, this is Internet curfew. It's not uncommon to imagine they'd shutdown Internet across border during any war (like against Taiwan).

- hackernewsdhsu 1y agoThat's what's so great about LoRA. Decentralized txt msgs, ultra cheap radios people run at home or wherever. $10-35USD ON AMAZON. Least txts get through.
- phantomathkg 1y agoIt won't get you from where you are to China though.
- wkat4242 1y agoNo but something like WSPR or FT8 would. Needs a license though.
- elevation 1y agoFT8 has such a small payload that you couldn't fit an emoji, much less an average English sentence. There's no authentication so anyone can pretend to be you. Traditional methods of verifying the sender (HMAC) would take so many hours to transmit that the physical propagation paths you're communicating through will probably collapse before you deliver the smallest verified message. If you need to communicate information, FT-8 is not for you.
- wkat4242 1y agoAgreed but if you're trapped in a war zone, time is one thing you have. And equipment for FT8 is simple to build yourself. It's also very difficult to trace. And you can take up some fields used for other stuff and convert them to data (like the sender). This would be illegal on amateur bands since it's required to identify oneself but again in a war situation this is less relevant since any covert communication will probably be forbidden anyway. You do need a time source though. GPS is generally used for that but it doesn't need to be extremely accurate with FT-8 like with some other protocols. I would imagine using it for a regular "I'm ok" message for the home front in such a situation using pre-arranged contents.
- cedws 1y agoCan you recommend a guide? I’m interested in trying it out.
- Gigachad 1y agoLook up Meshtastic. It’s kinda fun. Can chat with random people around you. But I don’t think it’s really that useful unless you have a really good spot like an antenna on your roof with no trees or buildings in the way.
- int_19h 1y agoIt's not that finicky in practice. I live in a heavily wooded area and I can still see plenty of nodes, some pretty far away. Trees are actually somewhat helpful there because you can easily rig up a node up high by throwing a line over a branch.
- Gigachad 1y agoI live in the suburbs, not really any high rises around be but some townhouses, I can “see” 180 nodes, but I can’t reliably message my friend 1km away. I get a lot of messages on the public chat but if I send one it’s a 50/50 if it will be acknowledged by any nodes. I tried it while staying in a high rise hotel and the experience was great. Instant acknowledgement and super reliable communication
- int_19h 1y agoThat would be LoRa. LoRA is a different thing.

- downrightmike 1y agoAt a whole 3kbps and line of sight!
- kotri 1y agoLocal police already equipped with signal jammer cars. Usually only used in college entrance exam period. They also appeared in recent protest in Jiangyou city.
- eastbound 1y agoIn fact, it’s a common tactic to do something unusual, in a recurrent way, so people aren’t alerted when it happens for real. (When the Mossad stole 7 boats from a French port (that they had fully paid), they prepared a few months in advance by having the pilots start the engines every night at 23:00, pretending they needed it against the cold temperatures. When they day came, they started the engines and left, no-one saw it coming).
- vintermann 1y agoIt could also be a test to look for surprising things that break, in case they want to do this permanently at some later point.
- woooooo 1y agoHanlon's and Occam's razors point to it being a mistake by the GFW operators, imo. If it's on purpose, I think you have the most likely motivation.
- account42 1y agoYou shouldn't use razors haphazardly or you might cut yourself. A mistake that also weirdly increments some TCP fields for the three subsequent RST packets when that's not how the existing GFW devices behave would need some explanation before you could conclude it to be the most likely explanation.
- woooooo 1y agoA new hardware/software rollout is one of the more common breakage situations, though. It definitely could have been on purpose but my gamble is still on a fuckup with a new system rollout.
- mschuster91 1y agoIt was five boats [1], an good story nonetheless. Think whatever you want about Mossad, it can not be denied that these guys have balls. [1] https://en.wikipedia.org/wiki/Cherbourg_Project https://en.wikipedia.org/wiki/Cherbourg_Project
- wkat4242 1y agoCould you bring something like a starlink mini for backup i wonder? Id imagine this would be very worrying being stuck there as a foreigner in such a situation.

- methou 1y agoA friend of mine tried, no signal.
- NitpickLawyer 1y agoIf war breaks out, it'll likely be enabled.
- andrewinardeer 1y agoEntirely speculation.
- NitpickLawyer 1y agoOf course it is entirely speculation. But there are previous datapoints you can look at (i.e. iran).
- andrewinardeer 1y agoElon doesn't sell cars or Powerwalls in Iran.
- Helmut10001 1y agoStarlink are very low orbit. Easy to bring down.
- veunes 1y agoThe infrastructure for that kind of control clearly already exists. What's unclear is how coordinated or deliberate these events are versus being side effects of testing or internal changes
- outworlder 1y ago> Terrible, this is Internet curfew. If you think this is bad... You can't even have a blog in China without authorization. It doesn't matter if you pay "AWS" for a machine. It won't open port 80 or 443 until you get an ICP recordal. Which you can only do if you are in China, and get the approval. It should also be displayed in the site, like a license plate. The reason "AWS" is in quotes is because it isn't AWS, they got kicked out. In Beijing, it is actually Sinnet, in Nginxia it's NWCD You can only point to IPs in China from DNS servers in China - if you try to use, say, Route53 in the US and add an A record there, you'll get a nasty email (fail to comply, and your ports get blocked again, possibly for good). In a nutshell, they not only can shutdown cross border traffic (and that can happen randomly if the Great Firewall gets annoyed at your packets, and it also gets overloaded during China business hours), but they can easily shutdown any website they want.
- UltraSane 1y agoAWS in China also doesn't have the Key Management Service, which leads to me to conclude it must be pretty secure. I added an A record for subdomain and pointed it at Chinese IP addresses. I wonder if I will get that angry email?
- bawolff 1y agoOr they just dont want to be put in the position of having to give out keys. I think the real paranoid people use cloudHSM.
- UltraSane 1y agoBoth KMS and CloudHSM are FIPS 140-2 Level 3 and AWS claims they cannot read private keys from KMS. The main difference is KMS uses IAM and the AWS REST API while CloudHMS uses PKCS #11/JCE and a separate permissions system.
- nijave 1y agoThe docs say both use HSM. Under "Secure" in the accordion menu https://aws.amazon.com/kms/features/#topic-0 https://aws.amazon.com/kms/features/#topic-0
