SITE DOWN - WILL BE UP AND FULLY FUNCTIONAL WITHIN A DAY OR TWO
In the morning of 2006-05-31 the Swedish National Criminal Police showed a search warrant to Rix|Port80 personnell. The warrant was valid for all datacentres of Rix|Port80 and was directed at The Pirate Bay. The allegation was breach of copy-right law, alternatively assisting breach of copy-right law.
The police officers were allowed access to the racks where the TPB servers and other servers are hosted. All servers in the racks were clearly marked as to which sites run on each. The police took down all servers in the racks, including the non-commercial site PiratbyrÃ¥n, the mission of which is to defend the rights of TPB via public debate.
According to police officers simultaneously questioning the president of Rix|Port80, the purpose of the search warrant is to take down TPB in order to secure evidence of the allegations mentioned above.
The necessity for securing technical evidence for the existence of a web-service which is fully official, the legality of which has been under public debate for years and whose principals are public persons giving regular press interviews, could not be explained. Asked for other reasoning behind the choice to take down a site, without knowing whether it is illegal or not, the officers explained that this is normal.
The TPB can receive compensation from the Swedish state in case that the upcoming legal processes show that TPB is indeed legal.
TPB will be back soon, before you know it. ;)
UPD: The site is back up! XD The police regretfully handed back the servers after thoroughly going through them and discovering that there was no illegal material at all. It all turns out that Hollywood told the Swedish police to take action, so they did, despite Swedish laws. :P Hollywood has to understand though, that American law wont work here! Driving a torrent site is not a crime in Sweden, and hopeful never will be. Downloading itself is the only illegal activity, and how the hell are they going to arrest %10 of the Swedish Population?! :D Haha, yeaah,The worlds biggest torrent tracker is back, and now even bigger than before thanks to the media. 8)
