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.
Same happened to me, I learned on other releases that no news is good news usually in updates, if you see things busy it’s probably doing stuff - but this was a nail biter for sure. Very glad I skipped all the RCs.
