Scheduled Maintenance Windows through July 2020 Announced

All maintenance windows from July 2019 through July 2020 have been scheduled and posted to the UIS Business Calendar.

Each year, UIS partners with campus and System leaders to determine dates when enterprise and business systems can be brought down for maintenance. The University of Colorado is a busy university, so it’s not always possible to avoid all business cycles, but we strive to have minimal impact to campus operations.

The UIS Business Calendar is also used to plan maintenance events tied to projects and to document important campus and business cycle dates. This allows departments, faculty, and staff to identify enterprise system outages and plan accordingly.

Maintenance Windows

Non-production maintenance typically occurs on a Friday and production maintenance generally occurs on a Sunday. The standard maintenance window runs from 6 a.m. - 6 p.m. Non-production maintenance windows occur two weeks prior to production maintenance windows to allow time to test updates before putting them in the live environment.

There are exceptions throughout the year, dependent on the level and type of work required (such as fiscal year end or windows that include regular maintenance and Campus Solutions PUMs). Extended windows and those occurring on a non-standard day are requested ahead of time for confirmation with campuses and business offices.

Assume full production and development outages during windows, unless otherwise noted in maintenance window communications. Keep up to date on all maintenance window communications including updates and changes, full details on affected systems, and more by subscribing to Maintenance Matters.

Production windows

Production windows affect our "live" systems with real-time data used by students, staff, and faculty. When there is a production window, most systems will not be available to users, unless a production communication states otherwise. Windows that are outside of the normal maintenance window times or days of the week are represented in bold below.
