Federation is broken.
It's been broken for days - and that's not to say for months, because I charitably include the few hours it worked again lately for some reason.
I don't know if other instances are that thoroughly broken, because the rest of Lemmy seems to be chugging along just fine. It's just us poor SDF user suckers.
And no-one gives a rat's ass.
Truly pathetic...
Yep. That's a new feature of 0.19.x. It reworked how the federation works, and now it also checks if stuff federated successfully, if not, retry. It was done to make federation more reliable. But of course, new features, new bugs.
At least that's as far as I know. Don't trust me.
