Yes, as it was said...
Here is the article from Wikipedia.
As of Tuesday, 25th September 2007, Demonoid is down, with no prior warnings from any moderators of the site. Both the main torrent page and the forum (fora) are no longer accessible.
Torrentfreak.com has since reported this is due to legal actions from the CRIA (Canadian Recording Industry Association) who ordered Demonoid's ISP to shut down the site.
And here is the whole article from TorrentFreak.
Demonoid.com, one of the most popular BitTorrent trackers has allegedly been taken offline by the Canadian Recording Industry Association (CRIA). Both the tracker and the website have been unresponsive for nearly 24 hours now.
Demonoid Shut Down by the CRIAAs of now it is still unsure what exactly happened, but the popular Dutch news site nu.nl reports that the CRIA is responsible for the downtime.
TorrentFreak contacted some of the Demonoid administrators, but they are not sure what happened either. It is certainly possible that Demonoid’s Canadian ISP pulled the plug after being pressured by the CRIA. The Demonoid server is still pinging, but the ISP could have firewalled the everything after they received some serious legal threats. Deimos, the founder and the head admin of the site is unreachable and has not responded yet.
This is not the first time Demonoid suffers major downtime due to pressure from the anti-piracy lobby. Demonoid had to move its servers from The Netherlands to Canada in June after The Dutch anti-piracy outfit BREIN filed a subpoena against Demonoid’s ISP. BREIN had asked the ISP to take Demonoid offline and hand over the administrator’s personal details, but Demonoid relocated their servers before any harm was done.
Unfortunately, it now seems that Canada is not the “safe haven” as they expected it to be.
Demonoid tracks over a million .torrent files and is the second largest BitTorrent tracker after The Pirate Bay. The shutdown of the site and tracker is a huge blow for the BitTorrent community that lost 2 of the most popular BitTorrent trackers (TorrentBox was taken offline for US users a few hours ago) within 24 hours.
