Bahnhof is a Swedish Internet service provider (ISP) founded in 1994 by Oscar Swartz in Uppsala, Sweden, and is the country's first independent ISP. Today the company is represented in Stockholm, Göteborg, Uppsala, Borlänge, and Lund.
Bahnhof was founded in 1994 by Oscar Swartz. It was one of Sweden's first ISPs. The company is publicly traded since December 2007 under the name BAHN-B (Aktietorget). On 11 September 2008, Bahnhof opened a new computer center inside the former civil defence center Pionen in the White Mountains in Stockholm, Sweden.
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.
After the whistleblowing website WikiLeaks was kicked off of Amazon Web Services in December 2010, it bought server space from Bahnhof, as its chairman Jon Karlung revealed in press interviews after in the light of the new controversy created by the leaks about the Afghan War, even showing journalists the two servers on which the data was held. The chairman said that WikiLeaks is treated like any other of Bahnhof's clients.
In April 2014, however, the CJEU struck down the Data Retention Directive. PTS, Sweden's telecommunications regulator, told Swedish ISPs and telcos that they would no longer have to retain call records and internet metadata. But after two government investigations found that Sweden's data retention law did not break its obligations to the European Convention on Human Rights, the PTS reversed course. Most of Sweden's major telecommunications companies complied immediately, though Tele2 lodged an unsuccessful appeal. Bahnhof was the one holdout and it was given an order to comply by November 24 deadline or face a five million kronor ($680,000) fine. In response Bahnhof offered all their customers a free VPN-service, thus making it impossible for Bahnhof to hand over customer data to law enforcement.
