At around noon on November 15, 2012, Xinhua announced the "List of members of Standing Committee of Political Bureau of 18th CPC Central Committee": Xi Jinping, Li Keqiang, Zhang Dejiang, Yu Zhengsheng, Liu Yunshan, Wang Qishan and Zhang Gaoli.
These screenshots show that, at 11:00 am that morning searches for "Politburo Standing Committee" (中央政治局常委) on Sina Weibo returned no results, just a censorship notice. At about the same time Xinhua published its announcement, however, Sina Weibo began returning results for that phrase.
