Why not load this website?

Why not load this website? Only 1 web site does not load? I contact the administrator ping sites and ran and came back with good results, I met one and came back with this: http://www.imagebam.com/image/3b3bc91566 … I have tried to Automatic proxy turn on, off (I've never had a proxy server to suppose it is intended to be off). I rebooted my wireless and ethernet. I Firefox downloaded and downgraded, downloaded Safari, Opera, Real Player and a browser. It works on any of them. However, on my PC works fine. I'm using Mac OS X Leopard and I I found a virus scan, updated my security settings and now a joke. Why is that not only work for everyone, but to me, but Why suddenly. And how can I fix it. Side note: It's a music fan site and has nothing illegal in it, and no adult material. Duuc.net works well, but that does not correct the problem. But thanks for your suggestion

this might work for u duuc.net
