It is just checking http://googlechromereleases.blogspot.com/2013/07/stable-channel-update.html http://googlechromereleases.blogspot.com/2013/07/stable-chan... to see if there was a release 'today' (in theory, taking into account time zones). Does not check to see if you updated today, which is slightly diff.
