While I understand the concept of federation I’m unclear as to what it actually entails at a technical level. When lemm.ee eventually shuts down, will all of that user content (posts, comments, votes, etc) cease to exist? Is it mirrored on other instances?
They will still be visible to federated instances as they have a local copy. But any new posts or comments will not federate.
And any new instance will not have a copy.
Ah that makes sense. So federation implies copying essentially, and not merely linking. Thanks!
