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.
I’ll check the new way Lemmy detects dead servers, it’s possible an outage caused lemmy.ml to think we’re dead (we’re not!) :-)
