Just in case anyone is using their account here to post to off-instance communities: those posts and comments seem to have a very high failure rate. There is a lot of activity and accounts on this instance. This is to raise awareness, not to pull people away or break up the lemmyverse. Quite the opposite really: there is a technical problem on this instance that might be preventing the lemmyverse from functioning as it should.
Good point. Nothing against the larger instance owners of course. If my little instance got super popular somehow (like being recommended in guides on how to join lemmy/kbin), and thousands of users got in per day, I could see issues happening just like this. I don’t know the ins and outs of tuning this software for performance at scale, and I know I couldn’t learn it fast enough if my instance faced very fast growth like lemmy.world has.
I think admins are going to need to turn registrations off periodically, as they scale their hardware (and their knowledge) to run it for more users effectively.
