 When the machine to which the failover IP (failover.forgejo.org) is routed is unavailable or to be shutdown, to the [Hetzner server panel](https://robot.hetzner.com/server), to the IPs tab and change the route of the failover IP to another node. All nodes are configured with the failover IP, there is nothing else to do.
