Demonoid, one of the biggest torrent sites around, was taken down on July 25 after a massive Distributed Denial of Service (DDoS) attack. The website is now completely unresponsive, although its administrator says he says he will bring it back eventually.
"I don't plan on shutting down, but if Im going to fix it I have to do it properly," the administrator told TorrentFreak. "That means upgrading a lot of our 7 year old hardware and maybe bringing up the beta only. You know how it goes with demonoid. It might take a while but it will come back."
If you want to offer your services to the cause, you're out of luck. The administrator does not want to accept help as he's worried about giving too many privileges over sensitive user data to complete strangers. It doesn't look like he's accepting donations either.
