On Monday, 2011-10-31 one of our VM servers died completely. This caused an unplanned outage for several customer VMs and our mail server mail.gocept.net. We were able to limit the total down times by migrating the affected VMs to other servers quickly.
It is unlikely that any data has been lost. Please excuse the service disruption.
The server started to decline network requests around 15:30 CET. Our stand-by support team was alerted immediatly. After we had come to the conclusion that we could not revive the hardware quickly, we began on 16:15 CET to move VMs to other Servers. Around 16:45 CET services have been functional again.
