Despite considerable efforts taken to provide physical protection of cables, North American networks still experience frequent cable cuts and outages. For more traditional networks of the type used for basic voice or data, outages can result in severe financial losses. Given the critical nature of many of the applications that emerging networks are intended to carry (medical-grade applications, first responder applications, etc.), the consequences of failure could be much more extreme. And yet the very sparse nature of many networks’ underlying infrastructure makes them inherently un-survivable. Resilience against widespread catastrophic correlated failures is virtually out of reach for modern public network infrastructures.

尽管采取了相当大的努力来提供电缆的物理保护，但北美网络仍然经常遇到电缆切断和中断。对于用于基本语音或数据的更传统的网络类型，中断可能导致严重的财务损失。考虑到新兴网络旨在承载的许多应用的关键性质（医疗级应用、第一响应者应用等），失败的后果可能更为极端。然而，许多网络底层基础设施的稀疏性使它们本质上无法生存。对于现代公共网络基础设施来说，抵御广泛的灾难性相关故障几乎是遥不可及的。
