2004 From this date to May 6th 2003 Web Rank Info's list from http://www.webrankinfo.com/google/go...ogle-dance.php is the source for the dates used. Web Rank Info's dates are a bit different than I found from other sources, (they are based on EU time and use a Monday date if the update happened over the weekend), but they are more complete.
I changed the EU Jun 23 date to Jun 22.
