Have Google watchers been overestimating the number of servers in the company’s data center network? Recent guesstimates have placed Google’s server count at more than 1 million. But new data on Google’s energy use suggests that the company is probably running about 900,000 servers.
Google never says how many servers are running in its data centers. The new estimate is based on information the company shared with Stanford professor Jonathan Koomey, who has just released an updated report on data center energy usage.
