BBC just reporting that ban on Google was lifted by the Chinese Government. Altavista, MIT, Columbia back in the air too. In fact, it appears at this time that no site is being blocked. Even http://www.harvardsucks.com has been removed from the blocked list, which I find insulting. Whatever happened to the old school pride?
As pointed out by Asian Business Intelligence, there appears to be some intermittency, I just got http://www.google.com and http://www.google4.com accesible, but not the other three #2,3 and 5 (9:44 PM EST)
