Lemmy.world has had endless issues with federation since upgrading to 0.19. It seems there are (right now) 97 instances where Lemmy.world is behind on sending outgoing federation.

We don't seem to have got any of their new posts for the last 12 hours or so. I'll flick someone from Lemmy.world a message and see if they are aware.

It seems it may be related to this new bug report: https://github.com/LemmyNet/lemmy/issues/4529

Basically when you get a steady stream of federation requests, at some point Lemmy can't keep up because of how each inbound federation triggers outbound requests to get other details. And they are run sequentially, so slow requests block the rest of the inbound federation requests as there's no queue.

It's slowly crawling along sending us updates but it's about 12 hours behind and may not catch up until the other side of the world goes to bed.

Plus it seems it has been getting much worse each day, now it has reached the point of being a problem, I'm hoping tomorrow is not a disaster 😐

Thanks Dave, I didn't realise that was the issue 😂

Yeah I just checked 'All' posts, there are not many top 'Active' posts from lemmy.world as usual

If you go to the link I posted above, look for the "lagging" instances, and find Lemmy.nz, you can see the last update.

It's about 14 hours behind, and getting worse. But it's not just us, Lemmy.world are looking into it.
