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.

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.
