I cannot view my blog.

I dont know what is happening, but the problem is that I cannot view my blog. I can still create or edit posts, but I simply cannot view it. When I was in Singapore, some of my friends in China complained to me about the same problem.
Is it because I am in China and I was blocked in some way, or is it because of the net connection I have now?I wonder if there is anyone else who can still view my blog.
