Resilience is the ability of the system to both absorb shock as well to recoverrnrapidly from a disruption so that it can return back to its original service delivery levels orrnclose to it. Recent manmade and natural disasters such as 9/11 incident and HurricanernKatrina have introduced an increasing interest in infrastructure resilience. The global submarinernfiber optics cable network that serves as the backbone of the internet is a particularlyrncritical infrastructure system that is vulnerable to both natural and man-made disasters. In thisrnpaper, we propose a model to measure the base resiliency of this global network, and explorernthe node to node and global resiliency of the network using existing data demand, capacityrnand flow information. The base resiliency of the system can be measured as the valuerndelivery of the system after a disruption to the value deliver of the system before a disruption.rnWe further demonstrate how the resiliency of the global internet infrastructure is enhancedrnthrough reducing the network vulnerability and increasing its adaptive capacity.
