What Happened When Mubarak Shut off Egypt's Internet 02/21/2011
Mubarak's first major attempt to squash the revolution was turning off Egypt's internet on Jan 28. This was shortly followed by an escalation of violence, and Cairo turning into a battleground between the revolutionaries and pro-regime thugs. What happened when the internet went down, and the future of Egypt hung in the balance?
The answer seems to be that the shutoff certainly had a large impact, but it wasn't nearly enough to disrupt the overall network.
