WHEN: December 2014 w/ January 7, 2015 Update
WHERE: Campus-wide, for certain network segments
Current Status: Open
Description: *Update* Working with our firewall vendor we have implemented a configuration change that we hope will mitigate the primary issues we have seen this past fall. The change is not considered a permanent resolution, however, if it demonstrates improvement over the next few weeks we hope it will be the basis for a permanent fix.
Over the last few weeks we have begun receiving reports of sporadic, though brief, disruptions to Internet access from many parts of the campus that have been increasing in frequency. In the course of troubleshooting this issue we ultimately identified an apparent root cause that stems from overloading our current firewalls beyond a specific technical limitation. We are working to identify solutions to mitigate this issue. Unfortunately, one of the corrections we attempted yesterday (Monday, December 8th) appears to have some unintended consequences that caused a technically different, but broader set of disruptions to occur. We have backed out the configuration changes and continue to pursue solutions to the original issue.
Service(s) Impacted: Internet access via Campus Network
Workarounds: None identified at this time
Estimated Time to Resolution or Next Update: Next update as new information becomes available.
Root Cause / Continuous Improvement: Under investigation
