I found one post from 12 hours ago that describes the problem: https://lemmy.ml/post/2650814 - but that’s all I’ve seen. Content is way down on lemmy.ml with nothing coming in from .world
EDIT: seems that lemmy.ml is getting some content delivered to .world, but .world communities seem islands on .ml that only have local new posts/comments.
Where does it say they’ve defedarated?
Seems like the federation is just broken for some reason, maybe load issues on Lemmy.world
