The 502 error with Lemmy.ml due to connecting with IPv6. Once I disabled that on my computer, everything loaded. See https://lemmy.world/post/120796
Something must have happened during the upgrade yesterday and DNS isn’t pointing correctly. Hopefully it is fixed soon.
Well, I am able to visit the site now
Shhhh don’t tell them that!!
It just says 502 Bad Gateway. I’m not even sure if the block is intentional on their part, or a server issue of some sort.
A 502 status code does sound more like an error from the server, yes. The correct HTTP status code for a block by the government would be 451. But I’m not sure if countries that try to block social media respect this, they probably want to hide the fact that that website exists entirely. So they might go for a 404 error instead.
I like that the code is 451, but yeah no one is going to explicitly use it when they’re blocking things. A little too on the nose.
404 is still a server response, so I imagine no response at all would be the way to go.
Yea true, so you would just get a timeout (or an error from the DNS server that the domain does not exist if you use a ‘government approved’ DNS server.
A lot of censorship-happy governments have specific message that show up when a page is blocked telling you quite explicitly that the page you’re trying to access is banned.
In contrast, in China you just get the browser’s default error page like you typed in a url wrong to a page that doesn’t exist, in essence they give you no error or indication info at all, just blank.
You’ll likely get a permanent redirect to some government site telling you access is denied. The same thing happens on a corporate or school network that blocked a domain.
@AndreTelevise Why is it blocked in your country? Is it your ISP blocking it or Lemmy.ml who doesn’t allow people from your country?
I’m not sure, but it is a 502 error so it’s likely just some server-related thing
@AndreTelevise
Yeah I got the same earlierUpdate: I think they fixed it now
@AndreTelevise yes they did :-)
I’m not sure that’s the case. Any country that blocks your end-user access to that server would also be blocking your local servers’ access to it too, after all its all just traffic to the firewall.Edit: Oh I get it now. If your country blocks access to foreign site lemmy.abc, but not to foreign site lemmy.xyz, you can join .xyz and subscribe to content from .abc. It will be interesting to see how quickly the whole fediverse gets blocked by strict countries now…
I suspect though that any differences in content most of us are seeing between servers at the moment are down to the massive load that they’re under. Generally the federation functionality seems to be the most processor-intensive and fragile part of the setup. I’ve also been able to access posts on struggling servers using apps that the native web front-end isn’t able to display.

This will be nearly impossible. Popular instances can be blocked but someone can simply create a new small one each time. It is eternal cat and mouse. Censorship by the country where it is hosted however will be effective for that instance but no other.
Are you sure? If the government here in NZ blocks Lemmygrad (IIRC hosted in Switzerland) would that stop my home instance (Beehaw which I think is hosted in the USA) from being able to access Lemmygrad posts?
No, it wouldn’t. The Beehaw server is located in the United States. External communities aren’t retrieved via your machine, but via their server.
@mykl @AndreTelevise Or even better you can use the ActivityPub like me to send a comment from Mastodon to Lemmy.
So if they block every instance in Lemmy, which is impossible by the way, you can still use other fediverse social networks to access to it.
Yeah, I was careful to say fediverse rather than lemmy for that reason. I think a sufficiently motivated party could still make access very difficult to sustain. Whether anyone’s going to be that motivated remains to be seen.
