GNU Social has proposed a mechanism for sharing a group between multiple instances: https://socialhub.activitypub.rocks/t/fep-8485-unbound-actor/2200
But as I understand it, it assumes such a group wouldn't have moderators at all
Comment on Does Lemmy have a way to counteract a mod taking down a whole community?

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.
Matrix is really a decentralised conversation store rather than a messaging protocol. When you send a message in Matrix, it is replicated over all the servers whose users are participating in a given conversation - similarly to how commits are replicated between Git repositories. There is no single point of control or failure in a Matrix conversation which spans multiple servers:

That would dramatically increase server resources necessary though

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).
