Ultra-modern Underground Data Center

The Hollywood-style Swedish data center, called Pionen, is managed by Bahnhof, one of Sweden’s largest ISP’s. The facility is located in a Cold War era nuclear shelter, deep in the bedrock, right underneath Stockholm city. It was designed to be able to withstand a near hit by a hydrogen bomb.

Unique Human-friendly Interior Design

The Pionen data center is like no other hosting facility in the world. It was inspired by old science fiction movies like The Empire Strikes Back & James Bond.

The facility boasts a unique human-friendly ambience, offering breathtaking waterfalls, greenhouses, a glass-enclosed conference room “floating” above the floor, and simulated daylight.

Backup Power

Backup power supply is ensured by two Maybach MTU diesel engines that were originally designed for submarines. They are capable of producing 1.5 Megawatts of power. Just for fun, a warning system (sound horns) from the original German submarine has been installed.

The cooling is handled by “Baltimore Aircoil fans producing a cooling effect of 1.5 megawatts”. This is enough to cool several hundred rack-mounted servers at a time.

24/7/365 Monitoring

Boasting 11,950 sq ft of space the data center houses a Network Operations Center (NOC) for all of Bahnhof’s operations.

One of five data centers, it is the largest and is manned by a 15 member team of senior technical staff.
