Reader Brian came across a new notice from Google this morning, in place of the Caffeine search architecture upgrade that Google's been letting users test out. It indicates that Google is starting to take its improved search database fully online.
Here's the text of Google's "error" page for Caffeine, as of this morning:
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 centre. This sandbox is no longer necessary and has been retired, but we appreciate the testing and positive input that webmasters and publishers have given.
Generally, our editors and readers have found improved search results from Caffeine, so having it start to spread around seems like a general win.
Thank you! [Google]
