Update II : we got the ip of data center that will respond about 50% of time with caffeinebased on this post from search engine land we now know that the ip of the caffeine data center is
188.8.131.52. ive updated my tool to compare the two flavors of search so it will use this new ip and it should return caffine results about half of the time. and again the release data is sometime after the holidays... Google has also been testing a new layout and i have speculated that it may be released when caffeine rolls out...
UPDATE: Google has finished its preview of caffeine and the tool no longer works...
our friend Matt Cutts has stated in his blog that caffeine wont be released until after the holidays and that they will be continuing to test the new version of caffeine transparently at one datacenter and that he will probably be releasing the ip of that data center (at some point) because the dev preview has been closed
We appreciate all the feedback from people who searched on our Caffeine sandbox.
Based on the success we've seen, we believe Caffeine is ready for a larger audience. Soon we will activate Caffeine more widely, beginning with one data center. This sandbox is no longer necessary and has been retired, but we appreciate the testing and positive input that webmasters and publishers have given.
this is old article text you can still read it if you like but caffine release date is quickly approaching and will soon be the standard google search...
so i just saw a update from the Google blog about Google caffeine its basically a different back end for their searches that should allow faster better and smarter indexing and updates.
