OpenStack Major Upgrade at RMA Region from 2020-11-23 21:00 CET to 2020-11-24 02:00 CET

In the hour after the announced maintenance window all DHCP servers were unavailable during around 30 minutes. This lead to newly created VMs not receiving any DHCP leases. Due to the much longer lease lifetime, already running VMs were not affected by this.

From Monday 2020-11-23, 21:00 CET to Tuesday 2020-11-24, 02:00 CET we will perform a major upgrade of OpenStack on our control and compute hosts in the RMA (Rümlang) region. Our Cloud Control Panel and API will remain active during this maintenance work. While in maintenance, the performance of the Cloud Control Panel and API may be degraded, and during short periods of time it may not be possible to launch new servers. Already running virtual servers and operations in the LPG (Lupfig) region will not be affected by this work.

Date / Time
Monday 2020-11-23, 21:00 CET to Tuesday 2020-11-24, 02:00 CET

Expected Impact
The performance of the Cloud Control Panel and API may be degraded during the maintenance. Thanks to our redundant setup no further impact is expected. Already running virtual servers and other regions will not be affected by this work.

We apologize for any inconvenience this may cause and thank you for your understanding.
