So the long-awaited Google Caffeine Rollout will be “going live after the Holidays” according to Matt Cutts.

“Back in August we mentioned a developer preview of Caffeine, which is new technology that improves our indexing infrastructure.

The feedback on Caffeine has been very positive, so we’re ready to move from the developer preview to the next stage of the roll out: going live with Caffeine at one data center. This means that a small percentage of Google’s users will benefit from the technology behind Caffeine in their regular searches.

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.

Most searchers wouldn’t immediately notice any changes with Caffeine, but going slowly not only gives us time to collect feedback and improve, but will also minimize the stress on webmasters during the holidays.“

Interestingly they are now taking into account “stress on webmasters during the holidays..”

- In the meantime the sandbox.google.caffeine site is now switched off and displays this message..

Thank you!

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.
