So I’ve been wondering, how do I see if I’m seing a post from a server that’s defederated from the instance I’m registered on? Like for example beehaw, which defederated from lemmy.world.
If you put /instances after the URL, e.g. beehaw.org/instances, it will list all linked and blocked servers.
This is actually surprisingly hard to do! People will get around to it I’m sure.
So far my most successful method is to googlefu my way through with keywords and browsing posts.
But, here’s some fun resources that can kinda-sorta-not-really help:
- lemmy.fediverse.observer/list
- lemmymap.feddit.de
The map in particular is extraordinarily cool but rather difficult to discern useful info from. I can tell you from it that lemmy.world is currently defederated by only one other Instance. Which is easy to figure out from there at this point.
Lemmy the software publishes all (de)federations of an instance at the /instances endpoint
For example, Beehaw’s (de)federations are at https://beehaw.org/instances
and my own single-user instance has them at https://lemmy.w.on-t.work/instances (which is slightly different as I run Lemmy 0.18)If you are looking for the reverse of this, there is a tool that shows that information, but the creators of it are suspicious to say the least (as in, will openly associate with KF kinda suspicious)
what’s KF?
This doesn’t quite answer your question but has some info on defederation - https://lemmy.world/post/149743
