From the China in Transition blog:
Bullog.cn, a blog site featuring intellectuals’ discussion over political, society and cultural topics, is suspended. Currently on its homepage is nothing but one notice that reads: “Bullog is going through additional procedures, and will reopen very soon. Please don’t worry.”
The website does not articulate what kind of “additional procedures” it is going through, but it’s not hard to imagine that they are likely related to government regulations over blog sites. Essentially, this note is suggesting that Bullog has been ordered by the authorities to stop operation and has to gain permission to reopen, probably after some adjustments to its content.
