John Heidemann gave the talk “Long-term Data Collection and Analysis of Outages at the Edge” at UCSD, San Diego, California on Feb. 8, 2013 as part of the CAIDA Active Internet Measurement Systems (AIMS) Workshop. Slides are available at http://www.isi.edu/~johnh/PAPERS/Heidemann13e.html.
This talk describes our analysis of outages in edge networks at the time of Hurricane Sandy, and how that work was enabled by long-term data collection. The analysis showed U.S. networks had double the outage rate (from 0.2% to 0.4%) on 2012-10-30, the day after Sandy landfall, and recovered after four days. We highlighted long-term data collection of Internet Surveys, a random sample of about 41,000 /24 blocks, and the characteristics that make that data suitable for re-analysis. The talk was part of the CAIDA Workshop on Active Internet Measurement Systems, hosted at UCSD.
This work is based on our recent technical report “A Preliminary Analysis of Network Outages During Hurricane Sandy“, joint work of John Heidemann, Lin Quan, and Yuri Pradkin.
