Facebook’s new data center in Forest City, North Carolina, officially opened today and is online and serving live user traffic.

The data center currently comprises two buildings: Building 1 broke ground in November 2010 and opened today, while Building 2 is expected to open later this year.

The facility takes advantage of technology developed as part of the Open Compute Project, launched by Facebook last year to drive more innovation and a greater focus on energy efficiency in the data center industry. Our Forest City data center will be the first live test of the Open Compute Project’s outdoor-air cooling designs in an environment where temperature and humidity conditions are considered to be outside the range of typical data center operations.
