Cannot access specific website in China

I used to use comcast but now switched to gigbit fios. I can sense that the response time of webpages gets slightly slower, even though the full time speed is much faster.

The most unhappy thing to me is now I suddenly cannot access a lot of webistes in China, or at very very slow speed, compared to comcast.

One example is www.52shici.com. I can access this website with my cellphone with absolutely no problem, but cannot access it through fios.

And I am so afraid to contact Verizon. Every time, some id***t just reset my service without solving the problem, causing a lot of temp pain on my side to wait for service back on line.
