Internet site access problem from Iranian

Hello, I need a web developer to test and find out why our corporate web site is unaccessable from Iranian. You should live in Iranian. Or at least have a VPS or VDS from Iranian. Our old web site was okay, but the new one is unaccessable. Probably there is a some kind of restirction about Iranian laws. Maybe it is about IP or content filtering, I don't know. You should make a traceroute and find out what the problem is. I am also a web developer. We will messaging in English and we will work in collaboration.
