About

Thunderping investigates the resilience of residential Internet connections before, during, and after routine and severe weather events. When the National Weather Service issues a weather alert for a county in the United States, we find IP addresses belonging to residential Internet connections in that county. We ping each host once every eleven minutes from ten different PlanetLab hosts, beginning up to six hours before the alert takes effect and ending six hours after it expires.
