Production Maintenance
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.
6 a.m. to 6 p.m. Saturday, May 30 production maintenance
Nonproduction Maintenance
Nonproduction 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 our customer base.
6 a.m. to 6 p.m. Friday, June 12, nonproduction maintenance
Environment Activity
UIS uses many development environments, which are identical environments to our production services to allow for testing.
Do you use our different development environments for testing? Check to see the schedule of current and upcoming environment activities. Note: You need to be on a CU VPN to access the spreadsheet.
