The web is still waiting for the worldwide roll-out of Google’s next-generation search infrastructure, the mysterious indexing system overhaul known as “Caffeine.”

A recent Wired profile of Google’s search team indicates that Caffeine has already been deployed. But it seems the technology is still limited to a single data center, and though Google had planned to roll it out to other facilities after the New Year, this has yet to happen.

According to Search Engine Land, a Google spokesperson says that Caffeine will roll out across the company’s global network of data centers “over the coming months.” Previously, über-Googler Matt Cutts had indicated that Caffeine would be rolled out to multiple data centers “after the holidays,” meaning after first of the year. And we’re now two months on from January 1.

In early November, after testing Caffeine in a public sandbox for several weeks, Cutts indicated the platform would soon be rolled out to a single data center for use on the company’s live search engine and that the company would follow suit with other data centers in a matter of weeks.

“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,” Cutts wrote on November 10. “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.”
