Mapping the Internet’s Sleep Cycle

Researchers from the University of Southern California’s Viterbi School of Engineering have mapped daily cycles of Internet use for nearly one billion IP addresses across the globe. The data, which is distinctly skewed toward U.S. and European activity, nevertheless shows what countries have the most dramatic differences between daytime and night-time connectivity. The researchers have speculated that this may be due to certain governments’ Internet use restrictions. The team hopes their work will inform other researchers developing tools to cope with massive Internet outages.
