True, I guess I don’t know how this works when it comes to federation. From what I understand, federation works by mirroring content from one server on another (so your local server has a copy of the remote communities, you interact with them on your instance and it then uploads any changes back to the original instance).
Does this mean that mirrored communities work as archives? If the original instance goes down, can you still browse the copy of it on any other instance that federated (and interacted) with it?
