On August 10 2009, Google announced an upcoming major improvement to the size, index, speed, accuracy, and comprehensiveness of their search engine index. This next-generation architecture, named Caffeine, was now available to the public on a temporary server for testing and feedback.
On June 8 2010, Google announced that Caffeine was live on all data centers.
