Purpose
Critics believe that the data center has the capability to process "all forms of communication, including the complete contents of private emails, cell phone calls, and Internet searches, as well as all types of personal data trails—parking receipts, travel itineraries, bookstore purchases, and other digital 'pocket litter'."
In response to claims that the data center would be used to illegally monitor email of U.S. citizens, in April 2013 an NSA spokesperson said, "Many unfounded allegations have been made about the planned activities of the Utah Data Center, ... one of the biggest misconceptions about NSA is that we are unlawfully listening in on, or reading emails of, U.S. citizens. This is simply not the case."

Reports linked the data center to the NSA's controversial expansion of activities, which store extremely large amounts of data. Privacy and civil liberties advocates raised concerns about the unique capabilities that such a facility would give to intelligence agencies. "They park stuff in storage in the hopes that they will eventually have time to get to it," said James Lewis, a cyberexpert at the

Toward the end of the project's construction it was plagued by electrical problems in the form of "massive power surges"
that damaged equipment.
This delayed its opening by a year.
The finished structure is characterized as a
Tier III data center, with over a million square feet, that cost over 1.5 billion dollars to build. Of the million square feet, 100,000 square feet are dedicated to the data center. The other 900,000 square feet are utilized as technical support and administrative space.
