Hmm... Half-caff seems to be gone at 18.104.22.168
22.214.171.124 is still displaying it though.
126.96.36.199 is not used for USA serps, you can clearly see the link on the page to go to google.com, it also says Google English on the heading. If you are at a true google.com page then it will never link to google.com, what you are seeing is results meant for google.ca or some other country.
Also there is also no such thing as 1/2 caff results. You need to use a web proxy that shows USA results to see the real thing. Out of the 20 or so proxies I use I am seeing the new results on over half of them and it seems to be growing.
