Routine Maintenance Periods

The Office of Information Technology schedules all routine maintenance to minimize disruption to University systems and services. The following routine maintenance periods have been set up to minimize impact on users. There may be time when maintenance falls outside of the established maintenance windows—this work is typically low-impact, isolated to select areas, or requested by a department—with prior approval by the OIT Change Advisory Board (CAB). 

General OIT Maintenance Window 5PM Friday through 12A Monday

AIS 6A Sunday - 12A Monday

SIS (Banner) 6P Saturday - 12P Sunday

Note: OIT avoids maintenance that affects the SIS Banner environment on Saturday from 10A - 6P.
