Back in August, WebProNews first told you about Google’s Caffeine update. As Matt Cutts told us then, the Caffeine project would provide improvements to Google’s indexing structure. Despite concerns from some users about the impact on search results, Barry Schwartz of RustyBrick told WPN that caffeine is in fact live at one data center.
He said the update was rolled out around 3 or 4 AM EST yesterday. Matt Cutts later confirmed the news in a blog post. Because it is only live at one data center, only a small number of Google users will experience Caffeine.
Although both Cutts and Google have indicated that there would not likely be a noticeable difference in search results, Schwartz says that any time the content in the index changes, the results will change as well.
In 2003, Google issued its Florida Update around this same time of year. Merchants and retailers were hit hard since millions of listings from the search results were reportedly dropped. Schwartz believes it is for this reason that Google is only releasing it to one data center. In his blog post, Cutts also assured users that the full launch would not take place until after the holidays.
While the location of the data center was not revealed, Schwartz expects webmasters to determine the specifics very soon.
What do you think about Google’s Caffeine update? Have you tested it? To what extent do you believe the search results will be impacted?

Whoops it is not live on any datacenter until after the holidays according to Cutts:

He will also tell us which datacenter (IP) so we can take a look in January.

When I tested Caffeine 2 months ago I noticed that there were more results returned that included universal search items such as images, video and news. All the more reason to make sure you tag all your online assets properly!

If you read what Matt said, Cafeine IS LIVE but only on one datacenter for the moment, the rest will roll out after Christmas.
Here’s an extract from Matt Cutts site:
I know that webmasters can get anxious around this time of year, so I wanted to reassure site owners that the full Caffeine roll out will happen after the holidays. Caffeine will go live at one data center so that we can continue to collect data and improve the technology, but I don’t expect Caffeine to go live at additional data centers until after the holidays are over.
Cafeine is live on one datacenter – it will fully roll out after Christmas.

It seems caffeine is running at 64.233.169.104 and other 64.233.169.XX ip block machines.
I’ve seen no impact whatsoever in our industry. Any clues or ideas when the full rollout will be? The test rollout showed one of my sites jumping to page one, so I am very anxious to see it in action.
