Comcast is dealing with a widespread outage of some of its services.

The company told CNBC, which it owns, that it is aware of a nationwide outage affecting some of its Internet, video and voice customers due to a fiber cut at a backbone network, which is a type of infrastructure that helps connect different computer networks, and was working to restore service. Comcast said in the statement it believes other providers were also affected.

An outage map compiled by Comcast showed that more than 3,300 of its customers in the Charleston area had lost Internet, TV and phone service by late Friday afternoon. Outages were widespread across the region, from Mount Pleasant to West Ashley.

On its website, Comcast said that the outage started when one of the cables that makes up the backbone of its network was cut.

Comcast's verified Twitter account replied to some users complaining about a lack of service. In the replies it said it was working to restore service and pointed users to the Xfinity service site for status updates.
