On November 8, 2012 all Google (Google.com, Gmail, Google Maps, Google Docs, Google Analytics, Google Drive) were blocked in China, according to The Next Web.
From November 10th, the search began to work itself, but many services were not available yet, but began to recover.
It is associated with long dispute between Google and the Chinese government that has been going on for years.
At the time of access lockout attempt to go to all the domains google.com, google-analytics.com, docs.google.com, drive.google.com, maps.google.com, play.google.com redirected to the Korean IP- address 220.127.116.11, which did not serve sites at all. An attempt to use an external DNS also did not work (for example, DNS 18.104.22.168 of the Google).
While blocking of the search lasted about 12 hours itself, it was called the largest in the history of Internet.
What a pity, Chinese people have lost access to their data at Google. Using Spinbackup they would be safe since they can work with their Google data withing Spinbackup account!
