The data center hosting Tier-1 sofia will carry out power maintenance tests on October 28th. This exercise serves to test the failover systems of the data center in case of a total power cut and for sofia implies a full shut-down of the cluster for the duration of the test.

The following services will not be available during the shutdown:

We will use this opportunity to carry out system updates on sofia and other maintenace tasks that cannot easily be done with the cluster online. A reservation is in place to ensure that no jobs will be running at the time of shutdown. Queued jobs will stay in the queue and will be automatically launched as soon as the cluster is back online.
