We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.

All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

Great Firewall took out all traffic to port 443 at a time Beijing didn't have an obvious need to keep its netizens in the dark

China cut itself off from much of the global internet for just over an hour on Wednesday.

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.

.ml is blocked in China not surprisingly.

just an hour in the middle of the night? sounds more like maintenance or an accidental block.

Or a test run to check reactions

Are we supposed to be glad they have the ability to do this?

[–] umbrella@lemmy.ml 1 points 2 days ago (1 children)

almost every country has the ability to cause an internet outage, accidentally or otherwise.

[–] Kolanaki@pawb.social 4 points 2 days ago (1 children)

Sharks in the ocean also have this ability.

also submarines of a given nation

Imagine all that propaganda that never reached its victims. So sad!

[–] marsza@lemmy.cafe 12 points 2 days ago

I doubt this is going to affect the propaganda machines’ Internet connection

[–] marduk@lemmy.sdf.org 17 points 2 days ago (2 children)

No mention of port 80 (HTTP) in the article... I wonder if they still had access to the internet, just without SSL?

[–] Danquebec@sh.itjust.works 3 points 2 days ago (1 children)

Also isn't there plenty of ways of using the internet that don't use either HTTP or HTTPS?

[–] First_Thunder@lemmy.zip 8 points 2 days ago (1 children)

Don’t a lot of websites enforce https at this point?

[–] GreenKnight23@lemmy.world 7 points 2 days ago (1 children)

nah mate, SSL is a fad. it'll be turned off any day now.

[–] marduk@lemmy.sdf.org 11 points 2 days ago (1 children)

I think AI has already moved on from that fad; every website I've vibe coded this week has only worked on http so far. You can check this one out if you want: http://localhost:3000/

Hey! You've copied that app that I've been working on, you dirty thief. Not even bothered to make any changes, either. Switch that off at once!
