Now Chinese user unable to visit feeds.feedburner.com, when I try to ping feedburner from China, it will return "Request timed out".
When I issued traceroute requests to feedburner in China, I found the IP packets are blocked by 18.104.22.168. This IP address is a main router of China Telecom.
It's confirm that the Greate FireWall's IP blocking works. The FeedBurner is blocked in China again.
This is not the first time that Chinese authorities blocks FeedBurner, in August 1,2006, FeedBurner is also blocked temporarily, one day later it's came back, but now it's blocked again.
Why Chinese authorities blocks FeedBurner? Because Feedburner provides content from countless websites. It could conceivably carry some information the Chinese authorities think it shouldn't. So they try to blocks it, Although this will let them be against lot's of Chinese bloggers.
Although the Chinese bloggers could visit FeedBurner via proxy server, only few people use proxy in fact, maybe because proxy is slow and instable.
I wish FeedBurner will come back tomorrow.
