Well, Technorati have confirmed on their blog that they are having reports of being blocked in China.
The story has also been picked up on many other blogs and sites such as this, this and this.
I wonder who is going to be next out of the search engines and listing sites. Maybe it would be a good time to set up a book - who will give me odds on it being Ask Jeeves?
Update April 28th: It looks like we are back on with Technorati. I am able to connect through without a proxy this afternoon. I last checked at about 11am and couldn't get through, but now at 1pm I am getting back on. Maybe the China Net Nannies had a change of heart!
I thought it would be a good idea to share what camera gear I use. I use a Canon EOS500D with EF 28-135mm f/3.5-5.6 IS USM zoom lens and EF 50mm f/1.8II. 
The rest world should try this, ban all IP in China and see if CCP can live with that.
