Network connectivity under investigation
Incident
Report for IT
Postmortem
On November 15th, the primary fiber connection between Lincoln and Omaha was severed causing a brief network outage for the University. This incident also forced all Network Nebraska traffic to route on a slower network link causing significant network congestion. Lumen was able to identify the cause of the break, caused by a rodent, and had it repaired by the end of the day restoring all network traffic to the expected paths.
Resolved
All systems are operating normally. This issue is resolved.
Monitoring
All issues appear to have subsided, and all systems are performing as expected. We're continuing to monitor for any reoccurring problems.
Update
The third-party vendor has identified the location of the fiber cut and is currently on site to make repairs. ITS continues to implement mitigations to limit the impact of the current outages.

Identified
ITS has identified a fiber cut in a third-party provider's connection as the cause of the issues, and steps are being taken to remediate impact to affected services. Most facilities on the Kearney, Lincoln, and Omaha campuses have at least limited connectivity at this time. Workarounds are currently being implemented to restore connectivity to some Outstate and Network Nebraska locations that remain offline at this time.
