Starting in January 2009, Google started directing UK users to our co.uk site, US users to our .com site, and Indian users to our .in site. The sites are identical other than regional spelling differences. Before January 2009, Google was sending almost all the traffic to the .com site, but the .com site didn't appear to be penalized in any way.
