The National Security Agency/Central Security Service (NSA/CSS) has identified a facility in San Antonio, Tex., as the site of a data center. 

Determination for the site was made after a comprehensive evaluation of potential locations nationwide, using input from government organizations, such as the Army Corps of Engineers, and commercial data center plans.

NSA has also engaged other government agencies to pursue the suggestion that Intelligence Community organizations collaborate to determine the potential for shared data center sites.

The agency has been described as described as the world's largest user of supercomputers. According to one press estimate, its yearly electric bill is US$21 million.

Most NSA/CSS employees, both civilian and military, are headquartered at Fort Meade, Maryland, centrally located between Baltimore and Washington, D.C. Its workforce represents an unusual combination of specialties: analysts, engineers, physicists, mathematicians, linguists, computer scientists, researchers, as well as customer relations specialists, security officers, data flow experts, managers, administrative officers and clerical assistants.
