Earlier this week, the world’s largest social network Facebook opened a data center on the edge of the Arctic Circle in the Swedish city of Lulea. The place was not chosen by chance: a subarctic climate, which will help make the energy consumption for cooling servers minimal. This is the first data center outside of the U.S., and Facebook calls it “one of the most efficient in the world.”

This is the place where he lives with the social network audience of 1 billion people.
