Last weekend I looked up L.Jianyong, we were roommates when we were students in the university. He is post graduate student in Beijing University of Chemical Technology.

We talked a long time, because it is donkey’s years since we have seen each other. Then, jianyong asked my blog, I opened computer and run FireFox, typed the URL… I found the blog can not be opened.

Night, I search about the survey of China Internet network bandwidth, the study surprised me:

There are 5 major internet service providers, China Telecom and CNC are most commonly used of all, CERNET for special educational institutions. CMCC and China unicom specially serviced for mobile devices. Their network bandwidth are:

- China Telecommunications Corporation (China Telecom): 135,321MB
- China Netcom Group Corporation (CNC): 89,665MB
- China Education and Research Network (CERNET): 4,796MB
- China Mobile (CMCC): 5,750MB
- China unicom 3,652MB

So, it’s not difficult to understand that why I can’t open my blog in the university.
