Activist group Great Firewall Report spotted the outage, which it said disrupted all traffic to TCP port 443 – the standard port used for carrying HTTPS traffic.
“Between approximately 00:34 and 01:48 (Beijing Time, UTC+8) on August 20, 2025, the Great Firewall of China (GFW) exhibited anomalous behavior by unconditionally injecting forged TCP RST+ACK packets to disrupt all connections on TCP port 443,” the group wrote in a Wednesday post.
That disruption meant Chinese netizens couldn’t reach most websites hosted outside China, which is inconvenient. The incident also blocked other services that rely on port 443, which could be more problematic because many services need to communicate with servers or sources of information outside China for operational reasons. For example, Apple and Tesla use the port to connect to offshore servers that power some of their basic services.

No wonder there were so few Chinese sourced hack attempts in my corporate F5 firewall logs last night lol.
Someone should post this in one of the tankie instances. Should be some good content for !meanwhileongrad@sh.itjust.works
Enjoy the freedom of having the likes of Meta and Google pull another Cambridge analytica. Or the freedom of having multi-billion dollar companies like YouTube aggressively push algorithms that steer people down the alt right pipeline. Or the freedom of instagram mechanically and ruthlessly instilling in children as much body dysphoria and low self esteem as possible in the name of profit.
It was literally only two years ago that Meta
wasgot caught promoting racial violence in Myanmar. https://www.amnesty.org/en/latest/news/2022/09/myanmar-facebooks-systems-promoted-violence-against-rohingya-meta-owes-reparations-new-report/Any reasonable person can look at the heinous acts carried out by western tech companies in recent years and realize that the great firewall has been vindicated.
Edit: “CCP shill”, “whataboutism”, “two things can be bad”… come on folks, its time to start thinking of some new thought-terminating cliches. These are so 2023.
Ah yep, there’s the cope I was hoping to see.
I think they just copy paste this stuff.
You can tell because it’s a completely non-sequitur. They don’t even bother tailing their ramblings to the conversation currently being had. They just control + c, control + v it into place, and then act like they’ve achieved something.
Like clockwork 👌
Out of the frying pan and into the fire.
Hahahahhahaha!..…hahahahahaha! Thanks, I needed that.
It means lemmy.world was blocked, despite being available in China most of the time
>The freedom also includes bad stuff
Well duh
I wonder if this means less cheaters in multiplayer games.
How many games use HTTPS?
There’s that game where you made paperclips…
Anyone know why someone would use port 443 for anything other than https?
There’s lots of things that transport using HTTPS that aren’t websites in browsers.
websockets
To not get blocked by the great firewall
Happy cake day!
Pass thoses firewalls and other corporates proxy/VPN/… that block most ports. If what you build is at least partly used where user have internet access, you know this port is open. Even if 22, 8080 and all the others are closed.
Sometimes mandatory web proxies still allow direct connections to port 443 so as to not break https, which in return means as long as your connection is to port 443, that proxy will pass it through without interfering.
I used to run sshd on port 443 for this reason back when I regularly had to work from client networks.
Some ISPs block other ports, so if you want to host something, that might be your best option.
