You have to run and maintain several instances. What if one instance goes down forever?

Then all of its content was already synced to the other instances. And, you technically can re-activate the down instance's communities on another instance, if needed.

I didn't knew that content was cached on other instances. Wdym by re-activate? Can you migrate the community and its contents unchanged into another instance?

Everything on lemmy is synced (federated) to all other subscribing instances.

That is how i am currently reading/commenting on this post. I am interacting with the synced copy of the post and comments which was sent to my instance. As well- you are interacting with the copy which was sent to your instance.

I could technically flip a few values in the database and tell my instance that this is a local community, and I would then be able to manage it as such.
