VIDEO: Facebook boasts green data centre in Luleå, Sweden

From the outside, it looks like an enormous, anonymous 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. Welcome to the Node Pole, in Luleå, northern Sweden, the site of Facebook’s first data centre outside the US.

Inaugurated in 2011 and set amid a green pine forest, lakes and an archipelago.
