Fixed
The Cloud platform is entirely stable again and the faulty cluster node is being investigated.
Reported
Because of memory issues, our vColo Cloud platform automatically rebooted a larger part of vColo VMs hosted at SNT. VMs were being recovered between 12:40 and 13:54 UTC+01 (Europe/Amsterdam time), 1 hour and 14 minutes of downtime for the most extreme cases, although most VMs had 2 minutes of downtime on average. All VMs have safely recovered, and no (disk) data seems to have been lost. We apologize for the inconvenience caused.
