Blackout/Maintenance Periods

Blackout/Maintenance Periods

Standard Maintenance Windows

In order to maintain systems and equipment, ITS has regularly scheduled service outage windows. These are scheduled during a time with the lowest impact to clients. This does not mean an outage would occur during each window. Outages are only scheduled as they are required. Clients are notified in advance for planned outages.

The standard maintenance windows are:

Day of Outage Hours of Outage Total Outage Time
Every Wednesday 6am-7am 1 hour
Every Thursday 6am-7am 1 hour
Every Sunday 6am-11am 5 hours
Last Saturday in June 6:30pm-12:30am 6 hours
First Saturday in November 6:30pm-12:30am 6 hours
Last Saturday before March Break 6:30pm-12:30am 6 hours


Standard Maintenance Blackout Periods

There are also standard maintenance blackout periods when we will NOT schedule Maintenance. These align with Critical points annual university activity cycle to reduce the risk and impact of unexpected failures and service interruptions, and also to  reduce the risk of weekend or holiday work for ITS staff.

Registration Three days (non-consecutive) usually late March.  The days of registration and the business day prior are considered blackout days
