Please, before posting, we’ve seen a lot of these post saying X instance is down right now, or “is X instance down?”. The answer is probably, but it’s probably because Lemmy v0.19 dropped and it includes some downtime, upwards of an hour for all the migrations to finish.
Please, hold off on asking/posting for an hour or so. Your sysadmins are waiting for it to come back online.
Hijacking this to add: most Lemmy apps don’t have any new feature yet. The “scaled” sorting (=weighted subscribed communities) will probably make it’s way into the first apps around New Years, I’d guess.
