Large-scale service disruptions in communication have been observed in the past but are not well-understood. The goal of this paper is to gain a better understanding of disruptions in communication services in response to large-scale external disturbances such as hurricanes. In particular, Hurricane Ike is drawn as a case study, and heterogeneous data is obtained from networks, storm, and system administrators. Using the data, the authors first study network-wide disruptions and dependences among different unreachable subnets. The authors' findings show that 120 out of 230 subnets in their data set were unreachable, among which 88 subnets became unreachable dependently at a time scale of seconds or less than three minutes.
