Over the past 10 months, Google search has dramatically increased the number of sites around the world from which it serves client queries, repurposing existing infrastructure to change the physical way that Google processes web searches, according to a new study from USC.

 

From October 2012 to late July 2013, the number of locations serving Google’s search infrastructure increased from from a little less than 200 to a little more than 1400, and the number of ISPs grew from just over 100 to more than 850, according to the study.

Most of this expansion reflects Google utilizing client networks (such as Time Warner Cable, for example) that it already relied on for hosting content like videos on YouTube, and reusing them to relay—and speed up—user requests and responses for search and ads.

“Google already delivered YouTube videos from within these client networks,” said USC PhD student Matt Calder, lead author of the study. “But they’ve abruptly expanded the way they use the networks, turning their content-hosting infrastructure into a search infrastructure as well.”

Previously, if you submitted a search request to Google, your request would go directly to a Google data center.
