After seeing what happend on r/antiwork over at Reddit. Does Lemmy have a way to prevent somthing similar, like could another instance decide to preserve a deleted community and not have a single point of failure?
The same question can be asked if an instance suddenly closes down, can other instances keep the communities alive?
If an instance goes down, then pretty all much all data on that server will not be accessible. So the communities, posts and users on that instance will be gone.
Maybe lemmy can implement something similar to the matrix protocol.
So a community will remain accessible even if the homeserver goes down
Also wanna add, that if any servers have been federating with communities that live on a dead server, they will still have a backup of all those pushed posts and comments ( which starts happening immediately after one person subscribes to that remote community).
That would dramatically increase server resources necessary though
yep that is a problem.
