Summary Box: Facebook plans server farm, report

THE PLANS: Facebook will build a large server farm in northern Sweden near the Arctic Circle, taking advantage of the chilly climate to keep its equipment cool. That’s according to the Swedish newspaper Norrbottens Kuriren.

WHAT SERVER FARMS ARE: Servers inside data centers are the backbone of Internet services such as Facebook, which has an estimated 800 million active users worldwide. The servers store and transmit billions of status updates, links, photos and all the outside apps used by Facebook’s members.

THE DETAILS: City officials in Lulea have said they were in talks with an “American world-leading company” to build the 5-acre data center. They declined to comment Wednesday.
