> I'm going to reopen this one because the all machines shutdown is a valid case that does occur in the scenario of data center power outages.

I'm not sure mysql8 *can* recover (or is safe to recover) in that state without some manual intervention. Perhaps what's needed is an action to trigger `reboot_cluster_from_complete_outage` and a workload message to indicate that the cluster is 'out'?
