Columbia, SC (WLTX) -- Time Warner Cable's Internet service went down for a good portion of the country this morning. The cause was purported to be planned routine maintenance that went awry.

According to Time Warner Cable's "TWC Help" Twitter account, they have been working to restore the internet service to affected areas as quickly as possible.

Reports began surfacing just after 3:30AM ET Wednesday on Twitter that a large portion of the U.S. was experiencing the outage.

The outage affected the entirety of Time Warner Cable's network. Time Warner Cable operates in 29 states and has 11.4 million high-speed Internet customers.

A check of the website downtetector.com just after 7:00AM ET shows that major population centers through much of the northeast corridor of the U.S., Southern California, and the east coast were still experiencing no internet service.

Included in the affected area is part of South and North Carolina.

The website is an independent service that runs automated checks on service providers of all sorts, from internet providers like Time Warner Cable, to specific services such as GMail, Twitter, and YouTube.

TWC has no estimated time that service will be restored, but a visual check of the map shows service slowly coming back online.
