It already placed. Matt has already mentioned in his blog post.

 

How is google caffeine?

 

I think it's being rolled out at the moment.

 

The actual Caffeine infastructure change has already been put in place. Now what we are seeing finally roll out is the algorythm changes we have been watching on the test data center.
