Good question. Not sure what the best procedure might be here. Could be as simple promoting them in order of initial mirror deployment dates and the others become mirrors for the newly activated instance.
Triggering the activation could be a part of an instance decommissioning procedure where the operator selects the mirror to become the successor. Maybe there could be some basic system specs and network performance reporting so they could choose the optimal instance. Users would receive a message that their account is being moved to another instance and domain.
In the event of an unexpected outage, there could be a deadman switch style timeout where the fastest mirror activates automatically after the original instance is out for long enough, but also a process for the operator of the downed instance to delay the takeover by signaling, "I'm working on it." In the event of automatic takeover, since users wouldn't be able to receive messages, there would have to be some sort of global lemmy notice system so users of the downed instance know where to go, like a sticky post on the front page or maybe just a separate "notices" page.
