Optical Transport RingLink between DSM and Ames: Loss of signal
We're seeing loss of signal between our DSM and Ames locations. We are investigating.
Our dark fiber provider has finished splicing the damaged fiber and are hands off. All links have been restored.
Crews have finished pulling cable and the west side of the fiber has been completely spliced. Splicers are now working on the east end and started around 2:50 PM CT. Services should begin to restore with each splice. Estimated time of resolution has been set for 5:00 PM CT.
Our dark fiber provider has confirmed that a contractor damaged the fiber while doing unrelated work.
Crews are onsite working to expose the damaged fiber to evaluate next steps.
There is no ETR at this time.
