LAWRENCE, Kan. (AP) — The University of Kansas is working to prevent another internet fiber cable cut that crippled the campus earlier this spring, with some officials arguing for funding to build a backup system.

On March 29, construction crews accidentally cut a section of fiber, shutting down internet access across the Lawrence campus and wireless internet at the Overland Park campus. Phone service also was cut in some buildings. It also shut down state testing for K-12 student in dozens of states.

We’re sorry for the inconvenience and are working to fix the network outage caused by cable cut on @KUNews campus. Stay tuned for updates…

The Lawrence Journal-World reports a University Senate committee report estimates the cost to the university will reach seven figures but an exact amount has not been announced. School officials aren’t naming the company that cut the fiber but they insist the school will not be paying for repairs.
