CCR staff strive to maintain up-to-date and secure resources for the UB community.  In order to do this we plan monthly maintenance periods for the academic (UB-HPC) and industry clusters.  These clusters are offline on the last Tuesday of every month for maintenance, unless otherwise noted.  Downtime starts at 7am and is usually completed by 5pm.  Jobs are held in the queue unless otherwise noted by CCR beforehand.  Faculty clusters and lab servers have downtimes every 60 days.  Other services experience maintenance downtimes several times a year.
