I am in Dongguan right now (with China Telecom). Google Docs is not working today (it works sometimes – but need to hit the reload button a few times).
Google reader and Buzz are still ok. (don't know how long it will last)
I think China is randomly blocking Google services to harass their customers and probably push them towards more "compliant" companies like Baidu or Bing. Right now I am having trouble accessing Google translate. How anti revolutionary that may be.
Google docs is partially blocked in China. Only the mode without SSL is working.
