An Animation of Hurricane Sandy's Effects on the Internet in 2014

In October 2012, Hurricane Sandy made landfall on the U.S. East Coast causing widespread power outages. We were able to see the effects of Hurricane Sandy by analyzing active probing of the Internet. We first reported this work in a technical report and then with more refined analysis in a peer-reviewed paper.

We recently animated our data showing Hurricane Sandy landfall:

(HTML5/MPEG-4 video)

These 4 days before landfall and 7 after show some interesting results: On the day of landfall we see about three-times the number of outages relative to "typical" U.S. networks. Finally, we see it takes about four days to recover back to typical conditions.

Before landfall we see few outages.

On the day of landfall we see about three-times the number of outages relative to "typical" U.S. networks.

After about four days networks have recovered back to typical conditions.

This analysis uses dataset usc-lander/internet_address_survey_reprobing_it50j, available for research use from PREDICT, or by request from us if PREDICT access is not possible.

This animation was first shown at the Dec. 2014 DHS Cyber Security Division R&D Showcase and Technical Workshop as part of the talk "Towards Understanding Internet Reliability" given by John Heidemann. This work was supported by DHS, most recently through the LACREND project.
