From the outside, it looks like an enormous grey warehouse. Inside, there is a hint of the movie Bladerunner: long cavernous corridors, spinning computer servers with flashing blue lights and the hum of giant fans. There is also a long perimeter fence. Is its job to thwart corporate spies? No – it keeps out the moose.
Welcome to the Node Pole, a hi-tech hub in Luleå, northern Sweden, and the site of Facebook’s first datacentre outside the US. The warehouse opened in 2013 and is set amid a green pine forest, lakes and an archipelago. The Arctic Circle is just down the road. A second centre next door is due to be completed later this year.
