In January 2010 Facebook announced plans to build its own data centers, beginning with a facility in Prineville, Oregon. This typically requires a larger up-front investment in construction and equipment, but allows greater customization of power and cooling infrastructure. The social network has since expanded capacity in Prineville and built data centers in Forest City, North Carolina, Lulea, Sweden, and Altoona, Iowa. It has been expanding capacity in each of those locations continuously by building additional data center facilities. The company is also building data centers in Fort Worth, Texas, Clonee, Ireland, and Los Lunas, New Mexico.
