It has already been widely reported that many Chinese are not happy with "Western" coverage of China and Tibet. Without going into the details, I suspect they have a point - these are complex issues and often cannot be reduced to simple sound-bites.

What is extraordinary about this is that it has resulted in ordinary Chinese citizens taking action - from a boycott of Carrefoure to a rumored Distributed Denial of Service (DDoS) against CNN.com that is going to take place today.

CNN is already reporting some mild disruptions of it's Asia service.

Update : Ethan Zuckerman is speculating that the Chinese filtering of CNN.com at the national level may have been done to protect CNN.com against the DDoS.
