Comcast officials believe an outage that affected many people in the Lowcountry Tuesday night occurred when a train clipped one of their fiber cables.

"It's one of those rare things that happens sometimes," said Alex Horwitz, vice president of public relations.

The outage occurred about 6:30 p.m., causing affected customers to complain on social media about losing television and internet service.

Horwitz declined to say how many people lost services but said the vast majority of customers were restored in three hours.

The outage came on the heels of a smaller outage in Walterboro. That one happened about 2 p.m. after it appears a logging truck cut one of their cables, Horwitz said.

It was also repaired in about three hours, he said.
