A massive outage for Verizon Wireless customers in Michigan this week has been blamed on a cut fiber optic cable.

The outage, reported Wednesday morning, mostly around Mid-Michigan, was fixed by about 9:30 p.m., but not without huge headaches from customers.

Verizon told WILX the cause of the outage:

"Verizon Wireless experienced a disruption in service for customers in parts of Mid-Michigan due to a fiber optic cable cut to one of our third-party fiber vendor's networks. The disruption was caused by an error made by the vendor, US Signal, during a renovation of the building that housed the fiber optic cable. This fiber cut caused disruptions to our primary and backup fiber paths. After discovering the problem, engineers were able to resolve the issue, and service was fully restored at 5:56 PM."
