Is it possible or does it present difficulties with federation?
I’m asking because today Vlemmy seems dead and people are speculating it has something to do with losing the domain name. So I want to know if there is a possibility the same server could come up again under a different domain but keeping the same accounts and content stored or if they will need to set up a new server and thus it’s just better to move on to another instance.
It will absolutely mess with federation. Accounts on the instance that moved should be relevantly unaffected, but anyone from external instances subscribed to local communities will need to subscribe to the new domain.
