FOREST CITY, N.C. – Facebook’s new data center in North Carolina is online and has begun serving live traffic, the company said Thursday.

The new server farm will provide Facebook with additional IT capacity to support its growing audience of more than 850 million users.

The North Carolina site is Facebook’s second data center, and features many of the designs used in the huge social network’s first company-built facilities in Oregon. This center will serve traffic in the eastern U.S. and Europe, according to the company.

Facebook also continues to operate data centers in leased space on both coasts.

Facebook broke ground in Forest City in November 2010. The project required 1.2 million hours of labor from 2,000 wokers, including construction crews and Facebook staff.

The social networking company has a second data center now under construction at the Rutherford County site 75 miles west of Charlotte.
