Alert: Campus-Wide IT Issues May Impact Online Services

August 27, 2019

To our campus community,

We are writing to inform you of some sporadic network-related performance issues the Campus Data Center has been experiencing that may impact services on campus. These issues began causing significant degradation to campus IT services at approximately 2:45 p.m. on Friday, Aug. 23. There was minimal disruption over the weekend but for significant periods of time on Monday, Aug. 26, many campus-wide systems were impacted by this issue. 

Impacted Systems

The following is a list of systems that have been impacted, others may be added:

  • bCourses
  • Bearbuy
  • Cal Answers
  • Cal Central
  • Imagine
  • Optometry and University Health Services (UCS) systems
  • Other general issues with downloading files, accessing shared drives, browsers freezing, etc.

Why is this happening?

The problem is an intermittent issue where delays in network traffic cause the systems to become inaccessible and/or to perform slowly. If you experience an issue using an online system, please check System Status to confirm the issue is actively in progress. If the issue you are experiencing is not listed as a known problem, please contact IT Client Services to report the issue. 

What’s next?

We understand the importance of having a stable network at this pivotal time of starting the fall semester. The network team and the teams supporting these services have been collaborating with the vendor to diagnose and resolve the situation. Currently it appears that the issues are related to resource exhaustion on the data center firewalls. We are engaged with the vendors of impacted systems, with their support, we will continue to work to restore system stability. Updates will be posted on the System Status page as more information is available.

Your patience and understanding during this time is greatly appreciated.
