Cloud Compute Nodes: OpenStack Major Upgrade, scheduled 7 months ago

From Tuesday 2018-06-12, 09:00 CEST to Thursday 2018-06-14, 17:00 CEST, we will perform a major upgrade of OpenStack on our compute nodes. All running virtual servers will be live-migrated to other compute nodes at least once during this maintenance work. This is a standard procedure during compute node maintenance and no impact is expected.

Date / Time
Tuesday 2018-06-12, 09:00 CEST to Thursday 2018-06-14, 17:00 CEST

Expected Impact
Thanks to the redundant setup no impact is expected. Already running virtual servers are not affected by this work as they will be live-migrated to other compute nodes before the upgrade. The network infrastructure is not changed during this upgrade.

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