- [Narrator] Sweden's largest internet service provider
is located somewhere you might not expect,
below 100 feet of bedrock in a former nuclear bunker.
The Pionen Data Center houses some of the most
sensitive information in the world,
which once included Wikileaks servers.
They can help protect their clients information
under Sweden's Free Speech Act.
Inside engines intended to be for German submarines
are used as backup generators.
The design and style is the work of CEO, Jon Karlung,
who took inspiration from his love of films.
He says that the choice to put plants in the caves
was to capture the computer meets plants vibe
of sci-fi films from the ’70's.
The plants are kept alive by grow lights.
The center has simulated daylight
and the waterfall,
well that's just for fun.
And while it may look like a villain's lair from James Bond
you won't find Goldfinger here,
just the 15 senior technical staff who run the servers.
