I have the same problem. I tried to get direct into the forums by hand typing "forum.daz3d.com" and still nothing.  Hand entering "www.daz3d.com" also was met with total fail.

I also tried to ping both and got back an average of 10ms times so the server's there and responding but the web site is failing to load. A trace route of both addresses also got back 9-10ms returns at every hop. 

Lets see how long it takes them to find out they have no web site at the moment and have to get dressed and run back to the servers to see what sploded. :P 

Oh and if it matters I tried with Opera and Firefox. Cleaned cache and cookies. Still nota.

My brain is just a toy box filled with weird things
