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.
I’ve heard reports from our users that liftoff stopped working when we upgraded on Sunday also. It apparently doesn’t work with the new version and they said the dev ran off to start a family.
