The Internet is central to our lives, but we know astoundingly little about it.
How big is the Internet? How reliable? How is it evolving over months?
How does it change over the course of a day?
Since 2006, we have been studying the public face of the Internet to answer these questions. We take regular censuses, probing the entire IPv4 Internet address space. For nearly two years we have been observing Internet reliability through active probing with Trinocular outage detection, showing that the Internet reflects natural disasters like Hurricane Sandy's landfall in 2012. Additional analysis of this data has shown that the Internet "sleeps": we can see that some areas have more active IP addresses during the day.
This talk will explore the science behind these ideas and trace their path from research to deployment.
