But how did the government actually do it? Is there a big kill switch inside Egyptian President Hosni Mubarak’s office? Do physical cables have to be destroyed? Can a lockdown like this work?
The OpenNet Initiative has outlined two methods by which most nations could enact such shutdowns. Essentially, officials can either close down the routers which direct traffic over the border — hermetically sealing the country from outsiders — or go further down the chain and switch off routers at individual ISPs to prevent access for most users inside. Egyptian authorities have taken a very careful and well-planned method to screen off Internet addresses at every level, from users inside the country trying to get out and from the rest of the world trying to get in.
“It looks like they’re taking action at two levels,” Rik Ferguson of Trend Micro told me. “First at the DNS level, so any attempt to resolve any address in .eg will fail — but also, in case you’re trying to get directly to an address, they are also using the Border Gateway Protocol, the system through which ISPs advertise their Internet protocol addresses to the network. Many ISPs have basically stopped advertising any internet addresses at all.”
Essentially, we’re talking about a system that no longer knows where anything is. Outsiders can’t find Egyptian websites, and insiders can’t find anything at all. It’s as if the postal system suddenly erased every address inside America — and forgot that it was even called America in the first place.
