An episode from kill switch:

On October 20, an Amazon Web Services outage knocked out big swaths of the internet — from Snapchat and Reddit to smart beds and government services.

But often, the frontlines are more local: a water plant, a 911 system, the power lines outside your window. In this CyberMonday crossover with WAMU’s 1A, we examine a small-town breach, the fragility of our digital infrastructure—and what it means for all of us.
