Cloud Compute Nodes: Security Updates to Address ZombieLoad, RIDL, and Fallout Vulnerabilities, scheduled 6 months ago

From Friday 2019-05-17 to Tuesday 2019-05-21 we will perform security updates on our cloud compute nodes to address the ZombieLoad, RIDL, and Fallout vulnerabilities. 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.

Date / Time
Friday 2019-05-17, 18:00 CEST to Tuesday 2019-05-21 24:00 CEST

Expected Impact
All running virtual servers will be live-migrated to other compute nodes prior to the installation of the updates on those nodes. However, it is possible that you may experience degraded server performance and/or short interruptions of network connectivity during live-migration.

Further Information
Details regarding measures to be taken can be found on our blog.

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