Liftoff!

May be it is on lemmy side. Many servers has insane user growth right now, so the servers struggled.

Looks server side to me. Got a maintenance notice from lemmy.world a little bit ago (after some pages and comments not loading), and liftoff was working well on another instance.

I've been switching between Liftoff, Connect, Thunder, and Jerboa, they are all having problems.

Liftoff has been very flakey for me all day, but wefwef has been fine so I don't think it's entirely down to server loads and the influx of new users. When Liftoff has completely failed to load posts or comments for me, clearing the app cache has fixed the problem, at least temporarily.

No wonder if everyone is just heading to the same few instances.

Seriously guys, make your accounts on servers that aren't stupidly massive already (lemmy's gonna need some time to catch up); it's all connected anyway, which is the entire point of decentralization

Use/recommend some smaller general ones at random like lemmy.one, lemm.ee, vlemmy.net; they've upgraded their servers for the surge of users too.
