It’s based on my understanding of how servers work and my tests. There is obviously always room for error, but I’m like 99% confident I’m right.
Also AFAIK lemmy doesn’t kick you out because you signed in elsewhere.
The good news is it only appears to affect lemmy.world. If you have an account on another instance, you should switch to that account for now.
No. This issue goes a lot deeper than your login information.
Could still be a software issue. Someone said this already but it could be possible that Lemmy.world is using a load balancer and multiple servers. These two servers’ authentication tokens may be out of sync. So if you hit server 1 and you are sign in to server 1, you’re good. If you hit server 2, you’re signed out all of a sudden. This can also explain why the issue started to happen abruptly today. It’s possible the load on the server wasn’t that bad yesterday so the load balancer didn’t kick in. This is all speculation. Will have to wait for an official message to confirm anything.
