Helpdesk request

The European ARC CalMS service ( will be unavailable from 16 - 30 October 2023.

The CalMS service runs on the European ARC cluster. This cluster will have two scheduled maintenance down-times during which also CalMS will not work. During these periods, you can still file helpdesk tickets to request calibrated data but the response will of course be delayed until after the down-time has finished (normal response time is between 1 h and 24 h).
