Derecho’s June scheduled maintenance will occur on Tuesday, 6/11 from approximately 7am to 7pm.  This outage is necessary to service cooling system components and has been scheduled in conjunction with vendor availability.

During this time, all Derecho login and compute nodes are expected to be unavailable. Shared file systems will remain available throughout the maintenance.   Scheduler reservations will be put in place to ensure that all user jobs have completed by June 11 as the downtime begins. Any jobs that are queued on Derecho when the downtime begins will be retained for execution when the systems return to service.

Our intention is to return all systems to service as quickly as possible, with a planning date of Tuesday evening June 11, however precise timing will be determined by maintenance events as they unfold. 

Progress will be communicated through the Notifier system throughout the course of the outage.
