One of the redundant RAID disks on our database server at Masto.host failed; this must be replaced immediately to prevent potential data loss if another disk were to fail. So Masto.host has taken Jawns.club offline, but they expect us to be up and running again in less than an hour. You can follow their thread about the maintenance on the official Masto.host account. You can also check "Database 5" on the Masto.host status page.

UPDATE: "There is a problem with the disk replacement that is causing the server not to boot." Downtime will be longer than expected.

UPDATE at 12:53pm Eastern: "The person that did the disk replacement didn't know that (EFI cannot be on the RAID), so they were hours attempting to reboot the server without EFI, until they gave up and handed me the broken server. Now, an attempt will be made to place the old drive back and see if the server boots like that and then I can fix the situation."
