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

> 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, the…

I laughed when I saw "Nginxia", thinking it was a portmanteau of, well, nginx and wuxia, a Chinese fiction genre. Reality is much less funny when I looked up NWCD, and you likely just made a typo of Ningxia.

Could 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.

You can still bring a foreign SIM card. 100% effective (via data roaming) at bypassing the firewall, but expensive.

In English, there is no continent named "America." It's unambiguously used to refer to the United States.

It could also be a test to look for surprising things that break, in case they want to do this permanently at some later point.

Hanlon'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.

You 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.

The most depressing is that what happens in China, will eventually happen in the west too. I'm sure certain US, UK, and EU bureaucrats are already crafting campaigns about how this ability will 'save the children' and that it should be implemented immediately (politicians and certain other selected people will be exempt of course).

Not only individuals, but also major companies were locked down. If this was a dry run for "certain measures" in the future, I can't believe how much of a blow it would cause to the economy. Therefore, I think this was more of a human error.

Determining the scope of the impact would also be part of such a dry run. And if it is meant to be used along some kind of military action then it's going to throw the economy into chaos anyway.
