This is a big problem. It creates the illusion that /c/cats on one particular instance is the real /c/cats.

This is the root of re-centralization and it must be pulled out.

    This is not a communication problem. Communities are indeed centralized and if an instance is shut down permanently or loses its data all the communities are gone. This is a big design problem of Lemmy.

    Edit: it’s sometimes possible to rebuild new communities on another instance and recover past messages that have been replicated on other instances (if there were full replicas) but this requires all users and moderators to agree on where to migrate and avoid splits and so on.

          Its actually possible to take the local copy, and set it as a local community…

          With a few database commands.

          So, migrating communities from offline servers is possible as long as it was federated and synced beforehand

            That’s besides the point. Of course it’s always possible to create new communities on new instances, and import posts from various sources, but the original community would be still gone.

            If an instance is shut down or becomes unusable for a long time there is no way to automatically migrate users to a new instance. Additionally, there is also no guarantee that all users will move to the same alternative instance. This can also cause unnecessary conflict around which alternative instance becomes the “legitimate” successor.
