For me right now when I do a search using this IP (which is the caffeine IP datacenter I believe) 184.108.40.206 [220.127.116.11] I get the new look of Google with the 3 columns and a totally different dataset (similar to the old sandbox url). When do the same search in google.com I don't get the new look and the SERPs are the same as before. I'm in the USA (west coast). When I use that caffeine IP I see significant improvements in my rankings compared to the regular google.com. Also I do hit that dataset on that IP on google.com about 50% of the time as well. So I'm hoping that will be the final dataset once everything settles down.
