Maintenance

Maintenance day on 05 October 2020

Maintenance will be performed on the entire cluster, i.e., it will be offline for the entire day. Please have a look below to see how this affects your jobs.

This is the current timeline for the maintenance day

  • Sun, 04 Oct. 2020 at 08:00 CEST: we will start to drain nodes, so that no more new jobs can be scheduled, but existing jobs can finish until the maintenance day.
  • Mon, 05 Oct 2020 at 08:00 CEST: any jobs that are still running will be cancelled. Therefore, you should make sure that your jobs will have finished until then.
  • Tue, 06 Oct. 2020: all nodes should be back running and the cluster will be available to you again. We expect that jobs that were in the queue but not yet scheduled will remain there until the cluster is back online, but we cannot guarantee this. Therefore, please check if your job is still in the queue when the cluster is back online.


We recommend that you check this page regularily for updates on the status of the cluster before, during and after the maintenance day.
