How Egypt Killed the Internet
In the case of Egypt, it was probably done with a few phone calls, says Jim Cowie, the co-founder and chief technology officer of Renesys Corp., a company that analyzes how the Internet is performing around the world.
Egypt severed mobile and Web communications late Thursday, the Journal reported.
Mr. Cowie said in an interview with Digits that he isn’t privy to how Egypt actually shut down the Web but outlined a scenario based on his “knowledge of how the Internet is structured.”
“People have talked about a ‘kill switch’” that would link to every router and be able to shut each one off from a central location, “but that is not realistic,” he said. “What is most likely is that somebody in the government gives a phone call to a small number of people and says, ‘Turn it off.’ And then one engineer at each service provider logs into the equipment and changes the configuration of how traffic should flow.”
