Freedom of Information movement none can claim to have held the banner quite as high as The Pirate Bay. They have weathered legal storms far greater than anything Napster or even Wikileaks have conjured up yet as i write this The Pirate Bay site is down. In an orchestrated attack, ISPs accross Europe were raided by police. A number of news sites reported that the site was up and running soon after the raids but this does not seem to be the case anymore. It seems like this was a solid effort to put them down for good but i'm sure this is not the last we'll see of The Pirate Bay.
Edit: Guess who's back up ;)
