What is "bahnhof"

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, Gothenburg, Uppsala, Borlänge, and Lund.

WikiLeaks used to be hosted in a Bahnhof's data center inside the ultra-secure bunker Pionen, which is buried inside the White Mountains in Stockholm.
