At approximately 15:40 UTC today, relay-1 experienced a kernel panic which caused the server to fail.
Engineers responded quickly and by 15:50 had already rebooted the server, which then proceeded to perform disk checks before returning to service at approximately 16:30.
We would like to apologise for this unscheduled outage, and are investigating the cause of the failure at this time. It may be necessary to apply a security patch to overcome this issue – and if we do so, this will be implemented overnight during the maintenance window.
