An issue with the I/O system of Hortense is causing performance problems. This might lead to file system lags and delays.
We are in contact with our vendor ATOS to come up with a solution.

In accord with vendor ATOS, several updates to hardware and software will be performed.
The following infrastructure and services will be unavailable during this period: Tier1 Compute Hortense in full, including all workernodes as well as login and debug nodes, and the dedicated Tier1 scratch filesystem.
During the maintenance, the (very) old Rome login and debug nodes (partition debug_rome) will also be decommissioned. This means that, after the maintenance, all login nodes will have Milan architecture.
