Unexpected reboot of one of the hypervisors Mon, 07 Jun 2021 09:00:00 +0000

At around 9:00 UTC one of hour hypervisors rebooted, causing unavailability of a couple of VMs/services, most notably our main website, bugzilla and nextcloud.

The VMs are started already and all essential ones should be up again.

All affected guests are now up again.
