According to my testing, starting from somewhere between 9:00 and 9:30 pm on June 24 Beijing time, all sites in the domain google.com were blocked in my neighborhood. The blocked services include the search service of google.com (except google.cn, which was still accessible), Gmail, Google Talk, Reader, Docs, Sites, etc.. The exact time of the recovery of the connection is not certain. BBC reports it was not resumed until today's morning; while some other source claims it was 11 pm yesterday night. The analysis on Kenengba, a blog in Chinese, is quite interesting, if you could read Chinese or would like to try some translating machines.
