Maintenance is scheduled to the Hortense Tier1 Compute infrastructure from Monday 14 (20:00 CET) till Friday 18 September 2026. A power outage to the datacenter hosting the Hortense system is already scheduled that week. We’ll try and take advantage of this to additionally perform maintenance and restoration works.

Tier1 Hortense will be offline during this period, including workernodes, login- and debugnodes and the dedicated Tier1 scratch system. If at all possible, we will limit the effective downtime as much as possible.
