I had to manually change a flag in the database to restore the community. There was no option from the UI to do a “restore” like you normally can. The user also deleted his account after maybe that is why.

Either way, what happened here can happen anywhere. And while there is always talks about “spreading the loading because it is good for the fediverse” it also shows what can happen if an instance’s admin(s) becomes inactive for whatever reason. We have lemmy.one and feddit.uk now who’s admins seem to have disappeared. Your community and accounts can be gone overnight.
