Thanks Delphy! I hadn't heard of Google's DNS before now! I still couldn't access MTS this evening, but I just tried it with Google Public DNS and it works.

I was having the same issue until today. I couldn't access the site for close to a month I'm on a mac so the flushdns option isn't something I know how to do here, this is the first I've tried accessing the site from work since I got the error, but I'll google the mac equivalent of a flush DNS, or maybe It's just been long enough that the DNS changed enough for it to work?! either way I MISSED THIS PLACE!!!
