Neither of my posts from yesterday and today have made it out to their communities’ home instance (lemmy.world), and neither has received any comments or votes. It seems like something to do with outgoing federation is stuck.
Edit to clarify:
The problem I’m seeing affects posts. I don’t know if it affects comments.
It’s possible that it only affects lemmy.world communities, but it definitely affects them even on other instances. Neither of these posts are showing up on any remote instance that I’ve seen:

6 days later, it’s happening again:
Hours wouldn’t raise my attention. I’m talking days.
Given that lemmy.world uses Cloudflare, I wonder if their server is overloaded enough to sometimes exceed Cloudflare’s 100 second timeout, triggering http-524 errors during federation.
