internet - Filtering drives internet traffic beserk

Internet traffic in, to and from China shows all signs of an upsurge in filtering that throws communication in disarray this weekend, causing potentially serious economic damage to the country.
The signals are irratic, as during earlier period when filter activity went up. In the past few days two China-based hosting services for weblogs were ordered to shut down and today some of the weblogs reporting on that activity seem down, while others like the Digital News China is down. The MSN chat services is now unavailable, while ICQ and Yahoo are working perfectly. Receiving email seems to problem, but pending emails are not leaving at this moment.
Filtering internet traffic, whether by governments, companies or parents seems to become such a nuisance for all users when it really starts to work, that the fall-out is worse than the disease it seems to be after.
