Downtime Schedule: 2022-2023 Academic Year

The following is a tentative maintenance downtime scheduled for the 2022-2023 academic year.  The majority of downtimes are the last Tuesday of each month but some may be moved to accommodate holidays or the academic calendar.  

Please note: This schedule can, and likely will change, to respond to vendor software updates, critical security patches released off-schedule, or unplanned problems.  We will update this page as soon as any decisions are made that affect the schedule.  Thank you for your understanding!

Types of downtimes:

Center-wide – all services at CCR affected

Cluster-wide – all clusters affected but no other services

Cluster-specific – some, but not all, clusters affected but no other services

Cloud – all cloud services affected but no other CCR services

FACULTY CLUSTER USERS:  Jobs on the faculty cluster are allowed to run up until the downtime starts.  Please ensure your jobs checkpoint and can restart where they left off OR request only enough time to run your job prior to the 7am cutoff.
