Very inaccurate, 95% of the requests would have cached those js files firstly, and secondly that is so mislead-ed its not even funny. they took the average cost of a DC and equipment in and and then added all Known dcs together to get to a magical number and say the only purpose of those DC's are to serve the internet. That paper is so inaccurate. The power cost of delivering 3 MB extra is minuscule on 99% of the networks. Only a hand full of people who use satellite only connectivity would suffer from 3 MB of extra data.
