Yeah, but beehaw said they are defederated. How are then their posts still visible?
Defederation means that posts and comments from defederated instances no longer appear on beehaw. I don't think it automatically means the reverse. You can even comment on a beehaw post, but your comment just stays on your Lemmy instance, it never goes to beehaw
So I can still see beehaw communities here and comment on them but if I do they won't show up to beehaw users?
If that's the case then we really need some indication/warning sign that the instance is defederated, or else people will be talking into the void if they don't keep close track of which instances are/aren't defederated.
I think so, i'm not 100% sure. Lemmy and kbin and others are built on the ActivityPub standard. That's a pull system. You comment on a beehaw post, then beehaw pulls your comment to beehaw so beehaw users can see it.
I'm not sure how your comment then appears on other instances, I don't know the protocol well enough. It could be that other instances pull your comment from beehaw. It could also be that other instances pull your comment from your instance.
Beehaw decided to stop pulling. In the first scenario the only people that see your comment are people on your instance. In the second scenario your comment appears everywhere except in beehaw itself.
So what happens if I reply to a comment from a beehaw user? It just wont reach? That seems like it will cause a lot of issues for users.
That is exactly what happens, but anyone from a different instance federated with yours would still see and be able to respond to your comment on beehaw's instance.
It sounds like a convoluted situation that will inevitably lead to a lot of confusion.
you are from lemmy.antemeridiem.xyz, which means beehaw.org still federates with your home instance. this only affects users of sh.itjust-works/lemmy.world <-> beehaw.org. also, i suspect already synced threads wont disappear, but new content won't be synced anymore (this part is just a theory, if someone who knows this could weigh in i would appreciate)
What do you mean synced posts? If instance 1 and instance 2 ar federated, do they each have a copy of the other's data?
Yes
@peril30 Probably cache
