Are some instances/communities closed off from others?

sonneedgym@lemmy.world to No Stupid Questions@lemmy.world – 78 points –

Still trying to get my bearings here.

My account is through Lemmy.World and when I visit the Movies and TV community through lemmy.world/c/moviesandtv@lemmy.film, I only see a few posts. But when I visit https://lemmy.film/c/moviesandtv, there's a lot more activity.

Did I mess something up in my settings or is this normal? Do I need to have multiple accounts for other instances?

Thanks, y'all.

lemmy.world has been defederated at least by beehaw.org. If you want to participate there you will indeed have to make an account in another instance. IDK about other instances though. Also sometimes posts don't propagate to other instances since population here just exploded. Lemmy's software stack is being developed to handle the higher demand better.

It would be cool to have some sort of federation map, that shows which communities have federated and which have not. Maybe it already exists?

EDIT: After a quick google I found this article

https://googlemapsmania.blogspot.com/2022/11/the-map-of-fediverse.html

that mentions

http://fediverse.space

which should show which instances are federated. But at the moment it doesn't seem to work for me. Just loads infinitely until "something went wrong" pops up.

lemmymap.feddit.de is a map that shows a few things. Clicking blocked shows the corresponding connections. It doesn't show the direction, but hovering over will show you an instances number of blocks. Some of the data could be wrong, though. Last I checked every instance is listed as no downvotes. The defederation with beehaw showed up pretty quickly though.

One note, maybe don't click the 'open' checkbox because that tries to show every connection and blows up my browser!

Oh nice, this actually exists. But not very usable - I just get a big cloud of text and it's very difficult to get a sense of what's being shown.

It's incredibly fiddly, lol. As a tool for understanding some of the fediverse's concepts I've found it marginally useful

Ah, for that, yes. But for checking status of certain instance connections, not really.

@Hedup Try https://lemmy.world/instances

Ah, thanks. Looks like beehaw.org is still federated with lemmy.world, but just in one direction since at https://beehaw.org/instances lemmy.world is in the blocked list.

Then they aren’t federated and likely won’t see posts, right? If instance A defederates from Instance B, no matter what instance B does, they don’t talk.

@MadCybertist @SonNeedGym @hydra @Hedup Yep. They might seem like there talking but you will be talking to yourself. They have to federate to be able to talk and see all there comments and post. you might see some stuff now cause its cached but once they reboot or whatever you won't see anything

I'm no expert here, but I believe Beehaw defederating from lemmy.world means that people on Beehaw don't see content from people on lemmy.world, and people on lemmy.world can see but can't contribute to content on Beehaw. If lemmy.world defederated Beehaw, it would go the other direction.

Yeah, that's pretty much what I meant by defederation in one direction.
