The question is why.
The BBC doesn't seem to have too much trouble coming to a conclusion as to why. http://www.bbc.co.uk/news/world-middle-east-12303564 internal communications are disrupted as are external commucations. from renesys http://www.renesys.com/blog/2011/01/egypt-leaves-the-internet.shtml At 22:34 UTC (00:34am local time), Renesys observed the virtually simultaneous withdrawal of all routes to Egyptian networks in the Internet's global routing table. Approximately 3,500 individual BGP routes were withdrawn, leaving no valid paths by which the rest of the world could continue to exchange Internet traffic with Egypt's service providers. <snip>
Moral of the story: Separate facts from assumptions and guesses. I did some Google searches and that region has had large scale disruptions in the past. Several cables follow the same path to the Suez canal and were hit.
my links through the region are all fine, but they don't jump off the cable in egypt just pass through.
