Networked Networks Are Prone to Epic Failure

A recent post from Wired takes a complexity look at the fragility of networks which are inter-related and thus increase their fragility.... a useful post:

Networks that are resilient on their own become fragile and prone to catastrophic failure when connected, suggests a new study with troubling implications for tightly linked modern infrastructures. Electrical grids, water supplies, computer networks, roads, hospitals, financial systems - all are tied to each other in ways that could make them vulnerable. Most theoretical research on network properties has focused on single networks in isolation. In reality, many important networks are tied to each other. Anecdotal evidence hints at their fragility, but the underlying mathematics are largely unexplored.
