Extended: Cloud Compute Nodes: Operating System Upgrade, scheduled 10 months ago

Despite thorough testing in our lab we discovered a few issues during final testing in production. These issues have been solved by now and we are proceeding with the maintenance work as planned. However, due to the unexpected delay, we have to extend the maintenance window by 24 hours (until Friday 2018-05-18 18:00 CEST)

Date / Time
Thursday 2018-05-17, 18:00 CEST to Friday 2018-05-18 18:00 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 and no network connectivity issues are expected.

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