Does the Internet sleep? Yes, and we have the video!
We have recently put together a video showing 35 days of Internet address usage as observed from Trinocular, our outage detection system.
The Internet sleeps: address use in South America is low (blue) in the early morning, while India is high (red) in afternoon. When we look at address usage over time, we see that some parts of the globe have daily swings of +/-10% to 20% in the number of active addresses. In China, India, eastern Europe and much of South America, the Internet sleeps.
Understanding when the Internet sleeps is important to understand how different country’s network policies affect use, it is part of outage detection, and it is a piece of improving our long-term goal of understanding exactly how big the Internet is.
See http://www.isi.edu/ant/diurnal/ for the video, or read our technical paper “When the Internet Sleeps: Correlating Diurnal Networks With External Factors” by Quan, Heidemann, and Pradkin, to appear at ACM IMC, Nov. 2014.
