Craig Labovitch via DeepField Blog: “While it is old news that Google is BIG , the sheer scale and dominance of Google in the Internet infrastructure has significant implications on network design and evolution. When we last published some large-scale measurements in 2010, Google represented (a now seemingly small) 6% of Internet traffic. Today, Google now accounts for nearly 25% of Internet traffic on average. Only Netflix has larger bandwidth, but Netflix peaks last only for a few hours each evening during prime time hours and during Netflix cache update periods in the early morning. By far the most striking change in Google’s Internet presence has come with the deployment of thousands of Google servers in Internet providers around the world. With little press coverage or fanfare, Google has deployed (Google Global Cache) servers in the majority of US Internet providers. By comparison, we observed GGC deployments mostly in Asia, Africa and Latin America when we last did a large scale study in 2010.”
