LOUISVILLE, Ky. (WDRB) - Humana has offered a reason behind Monday's system-wide network outage.

The company attributed the problem to an internal equipment malfunction. The outage left thousands of employees unable to get much, if any, work done.

The company's phones and website were also out of commission.

Many workers were sent home as a result of the system outage.

It also slowed response time for customers calling in with questions or concerns.
