Access to Tier-1 Hortense via SSH and the web portal has been restored. All partitions except for the debug nodes were already released 16/09 at noon, jobs that were in the queue started running then. A bit more work is needed to make the debug nodes available again.

Access to Tier1 systems is shut down with immediate effect. This is in response to a major security flaw in the kernel, which has been recently identified.

Access limitation applies to:

All these systems will not be reachable. However, running jobs will not be affected.

In the next few days, we will perform emergency maintenance procedures. If all goes well, the systems should be back up in the beginning of next week.
