Pionen - SE Datacenter

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.

Fully Redundant Network

Pionen is one the best-connected places in Northern Europe. It offers triple redundancy Internet backbone access.

Backup Power & Cooling

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.

Well-maintained & Reliable Servers

Pionen's network comprises multiple main production servers, backup servers, as well as administrative, spare and dedicated servers.
