The Wikileaks whistleblowing website has reportedly moved its server hosting to a Cold War bunker deep under the streets of Stockholm.

According to a Norwegian magazine that broke the story (credit to Forbes blogger Andy Greenberg), Wikileaks’ servers are now housed 30 metres (100 feet) underground in the 4,000 metre square Pionen White Mountains data centre, famous for a studied ‘James Bond’ design blasted from solid rock in the 1960s.

Said in its heyday to be able to withstand an H-bomb, with entrance doors made from 40cm (16 inch) steel, Pionen was remodelled by Swedish ISP, Bahnhof, two years ago.

The hosting arrangement was brokered by Swedish political party, the Pirate Party, some weeks ago, which is believed to be covering costs.

It is an appropriate place to co-locate Wikileaks’ servers on every level, including metaphorically. Days ago it was announced that Wikileaks’ founder Julian Assange is to be questioned over allegations of ‘molestation’ by Swedish authorities, which came in the wake of the site making public its hugely controversial Afghan War Diary of top secret NATO military and intelligence reports.

The site and its founder often characterise the organisation as under siege from outside forces, and an enraged US military establishment in particular.

The site is so secretive that a separate site has even been set up for people to submit secret information on Wikileaks’ backers, operations and inner organisation, all of which remain mysterious.
