Update - UIS continues the investigation into intermittent disruptions affecting multiple services.

While most services remain available, users may experience timeouts or error messages during login. Users are still encouraged to report ongoing issues to the UIS Service Desk and include screenshots with full URLs and error messages.

As a workaround, users should retry or refresh the page, as most login attempts succeed after one or more retries.

We will provide an update when any significant changes occur or as new information becomes available. #506446

Update - UIS is actively working toward a permanent fix of the performance and authentication issues affecting multiple services. Please continue to report any ongoing impacts to the UIS Service Desk by phone at 303-860-4357 or email at help@cu.edu during business hours. If you encounter an error, a screenshot that includes the URL is helpful. #506446

Update - UIS has implemented a temporary workaround to minimize user impact while they continue working toward a permanent fix in the coming week. Please report any ongoing impacts to the UIS Service Desk by phone at 303-860-4357 or email at help@cu.edu during business hours. Please provide a screenshot which includes the URL if you are able.

Current impact:

• Multiple services are impacted, most notably Campus Portals, though any application that relies on UIS infrastructure may be affected.
• Performance can be intermittent, with users reporting page timeouts prior to or after authentication.

Known workaround:

• If you are unable to log in, please try again or attempt access using a different browser. While performance is intermittent, most login attempts are successful at this time.

Teams will continue to provide updates daily or as significant progress is made. #506446

Feb 22, 16:41 MST
Update - Users may continue to experience intermittent performance and authentication issues affecting multiple services, including Campus Portals and other applications that rely on UIS infrastructure. Users may encounter slow loading times or timeouts during login attempts.

Teams have been actively investigating this issue throughout the day and will continue working into this evening and through Sunday. We will provide our next update on Sunday afternoon, or earlier if significant progress is made. #506446

Known workaround:
• If you are unable to log in, please try again. Some login attempts are currently completing successfully.

Feb 21, 16:03 MST
Update - Emergency maintenance has been completed; however, system behavior remains unchanged and performance continues to be intermittent. Our teams are actively investigating and will continue this work throughout the weekend. Additionally, the planned maintenance scheduled for Sunday, February 22, has been reassigned to support ongoing troubleshooting efforts.

ISS and UIS Teams will keep you updated with progress reports on Saturday and Sunday afternoons, or sooner if there is significant progress. #506446

Known workaround:
• If you are unable to log in, please try again. Some login attempts are currently completing successfully.

Feb 20, 17:52 MST
Update - Teams continue to actively investigate all potential causes and are working to identify the root of the issue as quickly as possible. #506446

Next Course of Action:
• To troubleshoot the network issues currently impacting various System and campus services, there will be a brief outage at 4 p.m. today. The duration of the interruption is expected to be between 5 and 10 minutes.
• During this time, anyone logged into an application that routes through UIS network infrastructure will be disconnected and will need to log back in once service is restored. This includes some applications that are hosted on the campuses that leverage UIS network infrastructure.
• Please save your work prior to 4 p.m. and avoid critical transactions between 4 p.m. and 4:10 p.m.

This outage is a necessary step as we work towards a resolution. We'll provide another update by 6:00 p.m. or sooner if there's significant progress.
