Bahnhof is a Swedish Internet service provider founded in 1994 by Oscar Swartz in Uppsala and was the first independent ISP in Sweden. Today the company is represented in Stockholm, Göteborg, Uppsala, Borlänge, and Lund.

Wikileaks is currently hosted in a Bahnhof data center inside the ultra-secure bunker Pionen, which is buried inside the White Mountains in Stockholm.[3][4][5]


Bahnhof was founded in 1994 by Oscar Swartz. It was one of the first Internet service providers in Sweden.[6] The company is publicly traded since December 2007 under the name BAHN-B (Aktietorget).[7] On 11 September 2008, Bahnhof opened a new computer center inside the former civil defence center Pionen in the White Mountains in Stockholm, Sweden.[8][9]


On 10 March 2005, the Swedish police confiscated four servers placed in the Bahnhof premises, hoping to find copyrighted material. Although these servers were located near Bahnhof's server park (in a network lab area) the company claimed they were not their property since they had been privately purchased by staff. They further presented evidence showing the material on these servers had been planted there by someone hired by Antipiratbyrån, a Swedish organisation fighting against copyright infringement.[10]

In December 2010, it was revealed that, having been kicked off their servers at Amazon, the controversial website WikiLeaks had also placed their data with Bahnhof. Jon Karlung, chairman of Bahnhof, one of the companies providing server space to the whistleblowing website, gave press interviews in the light of the new controversy created by Wikileaks leak of information relating to the Afghan War, even showing journalists the two servers on which the data was held. By the chairman's own admission, the data centre is essentially like any other, and WikiLeaks is treated just like any other client Bahnhof provides server services to.
