This June 6, 2013, photo, shows an aerial view of the cooling units at the NSA's Utah Data Center in Bluffdale, Utah. The nation's new billion-dollar epicenter for fighting global cyberthreats sits just south of Salt Lake City, tucked away on a National Guard base at the foot of snow-capped mountains. The long, squat buildings span 1.5 million square feet, and are filled with super-powered computers designed to store massive amounts of information gathered secretly from phone calls and emails.
