Host upgrades - NTT ZRH, scheduled 14 hours ago

To increase the capacity and redundancy of our network and VM offerings we plan a maintenance in Zurich, ZRH-NTT:

-Host upgrades of vmhost02, vmhost03 and vmhost04 - this may lead to short downtime of individual vmhosts of approx. 15 min.

Description: Host upgrades of vmhost02-04 at NTT ZRH - Services will be unreachable during the maintenance and will be available again afterwards.

Location: Zurich, ZRH-NTT:

Start Time Maintenance Window: Thursday, 2025-01-09 - 14:00 UTC +2

End Time Maintenance Window: Thursday, 2025-01-09 - 14:50 UTC +2

Update:

We are seeing an issue with disks on vmhost03 and are preparing a restore on a different node.

Post Mortem:

While the restore was started onto a different host system for VMs on vmhost03-zrh, we were able to get vmhost03-zrh back online using an older Kernel version. In order to avoid further impact VMs on vmhost03-zrh will be moved on a later to be announced date to new hardware. We apologize for the unplanned downtime caused.
