Use Internet Wayback Archive http://www.archive.org and see if I find any relics and artifacts of that website.
Either that or try and Google the website and see if a "Cached" version of the website is available from Google.
If neither, then I'm pretty much out of ideas. I'll look and ask around to see if the website is really shut down permanently or if the website is only just offline temporarily and is experiencing some technical difficulties.1
