Geographic Outage Animation
As referenced in the Blackout Results in Widespread Network Outages Report
Though a few networks did go offline earlier, the first burst of offline networks due to the power outage was indicated by BGP at about 16:11 EDT. A progressive increase, as shown in the animation, took place over the next few hours. The highest concentration of outages occured in the greater New York City area, as indicated by the inset. A representative 5% sample was used for this animation of U.S.-based outages. Note that network outages are not limited to the northeast--there are always some network outages going on somewhere in the U.S. (and the world) at any given time. Each network outage blip corresponds to an IP prefix (such as 192.168.0.0/16), each of which typically correspond to anywhere from 50 to 16k or more hosts.
