SuprNova.org and TorrentBits.org - two of the main servers used by the BitTorrent P2P network being targeted through the courts by the Motion Picture Association of America where both down this weekend. They are both key servers in the network, and the other smaller servers used by BitTorrent will have been taking the strain while they are out of action.
It is unclear if the servers being down has anything to do with the MPAA's legal action. If so BitTorrent is likely to look for servers outside the US and Europe whose owners are less likely to be concerned when the MPAA wins the right to fight P2P networks in the US Supreme Court.
