This is a completely different situation from the modest Internet manipulation that took place in Tunisia, where specific routes were blocked, or Iran, where the Internet stayed up in a rate-limited form designed to make Internet connectivity painfully slow. The Egyptian government's actions tonight have essentially wiped their country from the global map. What happens when you disconnect a modern economy and 80,000,000 people from the Internet? What will happen tomorrow, on the streets and in the credit markets? This has never happened before, and the unknowns are piling up.
