From a cost, operational, and routing perspective, the same would be true if you got a CT link in Los Angeles or San Francisco. I can't be sure (didn't try myself, sorry) but I think CT links are more filtered from outside PRC (HK being included in PRC) Since CT and CNC You mean China Unicom =) control all routes between China and everywhere else in the world-- including HK -- and the outsideCN-to-insideCN segment is going to be the most expensive and complicated element of any path between China and anywhere else, the choice of interconnect location with your preferred China-side service provider provider is largely going to be a matter of personal taste/local convenience. and when asking to go through the Great Firewall, you (I don't mean YOU, TV) should first focus on your objectives. Do you truly think that because you got a network foot inside Mainland China, your services will be easy to reach for all Chinese Netizens?
