Friday, July 20, 2018: 10:00 am (Booth): In 2016 and early 2017, tens of thousands of people gathered in camps on land near and on the Standing Rock Sioux Reservation in an attempt to stop the construction of the Dakota Access Pipeline. At one point, the camps made up the third largest "city" in North Dakota, and yet there was no mains electricity, telephone service, or plumbing. Law enforcement and private security used continuous "low intensity warfare" tactics on this temporary community on the plains. The Tech Warrior Camp, led by Geeks Without Bounds, built and maintained a wireless ISP for the camp, as well as providing other technical support for communications and digital security. They did this despite 60 plus mph winds and -20F temperatures. In this talk, you can hear about some of the lessons gained from that experience, along with models for building community ISPs that are resilient to both human adversaries and natural events.
