Ankra restarts a control plane only after it has been NotReady for about ten minutes, only when every other control plane is Ready and etcd keeps its quorum without it, and at most twice per node per day. It never stops, deprovisions or scales anything. Automatic restart is on for every cluster until a member turns it off. Readable by any member of the organisation.
