Somewhere in the middle. There’s a way to migrate your account to another server, including keeping follower relationships intact (so people don’t need to follow you again - they’ll automatically follow the new account). Past posts don’t get migrated though. If the old server is still running your past posts remain there. If the server just suddenly shuts down with no notice, though, there’s nothing you can do.
