Facebook CEO Mark Zuckerberg has published new pictures of the data center of social networks. The building is located in the town of Lulea in Sweden, 112 kilometers south of the Arctic Circle.

"There is no more efficient data centers in the world."

The town Luleå is surrounded by forests and icy rivers. View Facebook data center outside:

"I love this picture, it's like a scene from a science fiction film. Huge fans draw outside air for cooling of tens of thousands of servers. In winter when the temperature is lowered to -30 degrees, the situation is reversed: the heat from the body warms servers ".

"The data center is huge, but the idea of ​​its creation was born on the reverse side of the cloth. One night, an engineer Jay Park as sketched his vision of the system. "

150 people work here, but the rooms look like a desert. This is because for the maintenance of 25,000 servers need only 1 technician.

This is the first data center outside the US Facebook. It opened in 2013. Used for decorating the outside of the wooden panel.

The data center Facebook has an area of ​​six football fields.

The systems operate on energy, which comes from several hydropower plants. Data center 10% more efficient and consumes 40% less electricity than other similar objects.

"What is the difficulty in working here? Get to minus 30 to work. "
