Inside an underground data bunker


Originally built in the 1950s as a nuclear bunker, Iron Mountain's 'The Underground' high-security facility in Pennsylvania, USA, is now home to one of the safest data centres in the world.

2,700 people, many of them government officials, work in the facility under a limestone mountain - which holds everything from classified documents to old movie reels and valuable photograph collections.

But there has also been significant expansion in one area of the business: the storage and backup of online data in massive servers, or 'cloud storage'.

Ramon Goni tours the tunnels of The Underground with its vice-president Charles Doughty.
