A few months ago, when the Iranian government faced major nationwide protests, they turned off the internet for most of the population. Could that happen in the United States? This week, we chat with Dr. Karpoor Shashidhar and Dr. Cihan Varol of the computer science department at Sam Houston State about internet infrastructure at home and abroad. We also talk with Scott McHugh, program executive for the private sector at the Institute for Homeland Security, about the geopolitics of internet disconnection and access.
