Can’t post images because they’re too big so here’s imgur: https://imgur.com/a/Fm52ZTB
Edit: lemmy.ml and lemmy.world seem to have come back, I’m just a bit worried that it’s another one of those hacks.
Edit 2: Most of those I’ve tried came back. reddthat.com and sh.itjust.works seems to still be down
I get that message pretty much every time I visit a Community that I haven’t visited before (or maybe one that no-else from my instance has visited before).
It get fixed on a refresh (like the message suggests), so I’m guessing it’s a problem with time-out settings when my instance has to pull in a lot of new data.
That’s a different known issue when a remote community hadn’t been pulled locally yet.
