It's probably a combination of testing at scale on a server they control and wanting to get these features out so they can be iterated before a bunch of new users show up.
Wonder if I can finally sub to lemmy.ml communities…
From my remote instance, I've been subbing to lemmy.ml communuites about every 2 or 3 minutes, and it just now started to jam up. I'm speculating that the server restart fixed the problem for the first hour or so, but now it's back. Open GitHub Issue: https://github.com/LemmyNet/lemmy/issues/3101
I think lemmy.ml has more posts, comments, likes in the database due to historic reasons - and the backend is timing out, PostgreSQL not keeping up to application timeout. I have seen the problem on Beehaw, Lemmy.world when they are busy and throwing nginx 500 errors on their front page.
