Facebook is the second most visited site in the world and the largest social network on the planet with a total user base of over 2 Billion people .
Keeping all that data requires a large amount of data centers to keep user data secure.
It's located in a subarctic environment that allows the data center to have minimal cooling expenses. It is powered by affordable electricity that’s 100% renewable (12 hydro-electric plants at nearby rivers).
Employees sometimes have to go to the building in temperatures as low as -30°C (-22°F)..
The building's exterior looks futuristic.
The giant fans draw frigid air from outside into the data center to cool the thousands of servers. Heat from the servers also help to keep the employees warm.
About 150 employees work in the data center, but the giant halls are usually empty. Only 1 technician is needed for over 25,000 servers at one location, and they have to move around in the spaces using scooters due to the distances they need to cover.
Repairing a server requires just 2 minutes. Once a server gets old , they’re physically destroyed so that user data remains private.
