Amazon S3 suffered a significant outage on Wednesday in its US-East-1 region. This outage affected a number of companies in what seemed to be unpredictable ways. Yesterday a DNS outage at GoDaddy caused similar effects on availability of what otherwise seems like an unrelated set of Internet sites.

These resilience issues should be approached as part of risk management planning, but as our recent study in Ashburn VA highlighted, shared vocabulary for these types of informed risk decisions between customers and data center and network providers is often not adequate.read more
Nate Evans and Mike Thompson from the COAR team recently spent some time at the African Institute for Mathematics and Science (AIMS) teaching computer networking and cyber security to a cohort of 40 students. During our time at AIMS, we encountered many situations that made us think about how our research in resilience applies in a place like Senegal where we can't make any assumptions about steady state.read more
