This is view of the National Security Agency new data center being built in Bluffdale, Utah, U.S., on Thursday, July 4, 2013.
The NSA’s new data-storage center in Utah has suffered a series of mysterious meltdowns in the past year.
Officials told the Wall Street Journal that 10 fiery explosions, known as arc-fault failures, have ripped apart machinery, melted metal and destroyed circuits. The repeated meltdowns have delayed the opening of the one-million square foot facility by 12 months.
Investigators have not yet determined the root cause of the electrical failures, nor have they agreed upon a solution that could prevent the explosions from happening again.
