It appears that D-Addicts is once again having DNS issues. OpenDNS can't resolve the domain name on any of its servers.

Further studying the issue, it appears to be something regional... Can't go past LAX's gateways on the Time-Warner network when tracerouting D-Addicts' IP addresses. People in other regions more likely can access D-Addicts, but it appears that at least through the LAX gateway the routes are dead.
I must be in that region... I'm in Arizona... because both the forum and tracker pages have been dead for me the past 20 minutes or so.
Just a shot in the dark, but it couldn't be related in any way to the weird ISP that's been showing up on torrents and messing with the peer stats the past couple days, could it?
EDIT: Just now tried it again and it loaded, so something must've gotten resolved.
