Today, around~300 cables carry the majority of international Internet traffic, so a single cable cut can affect millions of users, and repairs to any cut are expensive and time consuming. Prior work has either measured the impact following incidents, or predicted the results of network changes to relatively abstract Internet topological models. In this paper, we develop a new approach to model cable cuts. Our approach differs by following <em>problems<\/em>\u00a0drawn from real-world occurrences all the way to their impact on <em>end-users<\/em>. Because our approach spans many layers, no single organization can provide all the data needed to apply the model. We therefore perform <em>what-if<\/em>\u00a0analysis to study a range of possibilities. With this approach we evaluate four incidents in 2012 and 2013; our analysis suggests general rules that assess the degree of a country&#8217;s vulnerability to a cut.<\/p><\/blockquote>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>We just released a new technical report \u201cA Holistic Framework for Bridging Regional Threats to User QoE\u201d, ISI-TR-2013-687, available as\u00a0https:\/\/www.isi.edu\/~johnh\/PAPERS\/Cai13c.pdf From the abstract: Submarine cable cuts have become increasingly common, with five incidents breaking more than ten cables in the last three years.
