CU Alert: All enterprise and business applications are available.
Portal Status: Green
All maintenance windows from August 2022 through July 2023 have been scheduled and posted to the UIS Business Calendar.
Each year, UIS partners with campus and System Administration 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.
Non-production maintenance typically occurs on a Friday and production maintenance generally occurs on a Sunday. The standard maintenance window runs 12 hours, from 6 a.m. to 6 p.m. Non-production maintenance windows usually 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. Extended windows and those occurring on a non-standard day are requested ahead of time for confirmation with campuses and business offices.
This year, UIS is introducing tentative production windows, on the weekend following a regularly scheduled maintenance window that requires complicated updates. We do not anticipate needing the tentative window but prefer that campuses are aware well in advance in case those windows become necessary.
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 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 outside of the normal 12-hour maintenance window times or days of the week are represented in bold below.
Non-production maintenance windows affect the testing and development versions of CU's production systems. These mirrored systems allow UIS staff to develop new features and functionalities and test them before they are moved to production for real-time access by CU’s students, faculty and staff.
These maintenance windows will affect Campus Solutions and student portals. Campus Solutions can also be down during scheduled production maintenance windows. These maintenance windows extend beyond the 12 hours of the normal maintenance window times:
