I found in China,www.chinatelecom.com.cn can internet with sagemath ,chinaunicom.com.cn cannot.chinaunicom EVEN all foreign college cannot,for example:washington.edu,http://www.harvard.edu/,http://wstein.org/.......

so chinaunicom is worse than chinatelecom!

I'm sorry that the internet between the US and China is weird, probably due to censorship rules, etc. I don't know if we'll ever have a version of cloud.sagemath that runs from within China, though I could imagine that happening at some point. I'm curious -- can you connect to the university website http://www.washington.edu/ ?
