Weather is a leading threat to the stability of our vital infrastructure. Last-mile Internet is no exception. Yet, unlike other vital infrastructure, weather’s effect on last-mile Internet outages is not well understood. This work is the first attempt to quantify the effect of weather on residential outages.

Investigating outages in residential networks due to weather is challenging because residential Internet is heterogeneous: there are different media types, different protocols, and different providers, in varying contexts of different local climate and geography. Sensitivity to these different factors leads to narrow categories when estimating how weather affects these different links. To address these issues we perform a large-scale study looking at eight years of active outage measurements that were collected across the bulk of the last mile Internet infrastructure in the United States.
