Where does WikiLeaks keep its secrets? In a former military bunker and nuclear shelter under Stockholm’s city streets. Nicknamed the James Bond Villain Data Center, this 8,000-server facility, which could theoretically withstand a nuclear impact, is protected by 24-hour video surveillance and a 2-foot-thick armored door. Two German V12 diesel submarine engines are on standby for backup power. Recycling a war room comes at a price, though: Bahnhof—the ISP that runs the data center—had to have the glass and frames for the walkway and conference room custom-cut to accommodate the curved walls and uneven ceiling.
