Is it just me, or are the implications of this fiber cut being greatly exaggerated. I was able to traceroute to an IP in Iran with no problem. Perhaps the lights have gone out for a large portion of the population, but their local hosting services are still up. (and yes, I checked to ensure that the server was physically in Iran and not hosted elsewhere) It's my understanding that the goal of something like the Internet is to have no single point of entry, so if one major fiber goes out, you still have alternate routes in place.
