Major movie studios have won yet another round against The Pirate Bay, this time cutting off one of the site's chief ISPs, Cyberbunker.

The district court in Hamburg, Germany has issued an injunction against Cyberbunker and its owner, Sven Olaf Kamphuis, demanding that he cut off service to The Pirate Bay. Failure to do so will result in massive fines of €250,000 per act of online infringement, or up to two years in prison.

The Motion Picture Association, the international version of the MPAA, requested the injunction and a judge concluded that Cyberbunker did not qualify for the "safe harbors" found in EU law, given that the hosting service had been notified about copyrighted movies listed on The Pirate Bay.

Cyberbunker is run by CB3ROB Data Services, a Berlin company. The company's website hosts prominent links to the Dutch and German Pirate Parties, along with "untraceable transit" and "privacy and diplomacy guaranteed."

"We go forward to defend freedom and all that is good and just in the world," reads the site. "The total solution provider in a hostile world!"

The Pirate Bay has proved elusive, shuffling its servers, ownership, and ISPs around the world in an effort to avoid the studios. Pirate Bay admin Fredrik Neij works for DCP Networks, a Swedish company that provides "a wide range of proxy services, tunneling services, DNS hosting and colocation," according to Neij. DCP has hosted numerous BitTorrent sites over the years and has tremendous experience at keeping them going.

Over the last couple of years, however, the studios have managed to secure the conviction of four key Pirate Bay defendants in a Swedish court, convinced several European judges to censor the site, and obtained injunctions against Pirate Bay hosts.

Despite it all, the site remains accessible, though the MPA promises that "litigation is continuing against other facilitators in Sweden who are hosting trackers."
