Maintenance · Ceres - All - Tuesday, October 13 · 2026
Ceres cluster maintenance is scheduled for October 13-14, 2025.
Queued jobs will not start if they cannot complete by 7 AM CDT on October 13. In the output of the squeue command, the reason for those jobs will state (ReqNodeNotAvail, Reserved for maintenance). The jobs will start after the scheduled outage completes.
The Atlas cluster will be available during the Ceres maintenance. We strongly suggest copying data from Ceres to Atlas or Juno prior to the maintenance if you plan to continue working through the maintenance. Once maintenance has started, we will not be able to move your data.
