Egypt's Internet goes dark during political unrest

Egypt has gone offline.
In a stunning development unprecedented in the modern history of the Internet, a country of more than 80 million people has found itself almost entirely disconnected from the rest of the world.
The near-disconnection--at least one Internet provider is still online--comes after days of street protests demanding an end to nearly three decades of autocratic rule by President Hosni Mubarak. Those followed this month's revolution in Tunisia, another country with little political freedom and high levels of corruption.
Jim Cowie, chief technology officer at Internet-monitoring firm Renesys, said that at approximately 2:34 p.m. PT, his company "observed the virtually simultaneous withdrawal of all routes to Egyptian networks in the Internet's global routing table." (See CNET's earlier coverage of network disruptions.)
"Virtually all of Egypt's Internet addresses are now unreachable, worldwide," Cowie wrote in a blog post this evening.
A major service provider for Egypt, Italy-based Seabone, reported that there was no Internet traffic going into or out of the country after around 2:30 p.m. PT (12:30 a.m. local time), according to an Associated Press report.
Al Jazeera English reported that the Mubarak government "denied disrupting communications networks" in advance of widespread protests planned at more than 30 mosques and churches on Friday, which is a day off in Egypt with banks and many businesses closed. (A spokesman for the Egyptian embassy has also denied that Facebook and Twitter have been blocked.)
While the cause of the disruption remains unknown, it's clear that yanking Egypt's Internet addresses was a conscious decision, not a fiber cut or a natural disaster. That means Egypt will be conducting a high-profile experiment in what happens when a country with a $500 billion GDP, one that's home to the pyramids and the Suez Canal, decides that Internet access should be restricted to a trickle.
That trickle can be found at the Noor Group, which appears to be the only Internet provider in Egypt that's fully functioning. (Cairo-based bloggers are speculating that its unique status grows out of its client list, which includes western firms including ExxonMobil, Toyota, Hyatt, Nestle, Fedex, Coca-Cola, and Pfizer.)
An analysis posted by network analyst Andree Toonk, who runs a Web site devoted to monitoring networks, shows that yesterday there were 2,903 Egyptian networks publicly accessible via the Internet. Today, there are only 327 networks.
Noor is "the only provider that doesn't seem to be impacted by this," Toonk wrote.
The Internet disruptions coincided with activist action. Anonymous, the group that launched distributed denial-of-service attacks on Web sites of financial institutions and others opposing WikiLeaks last year, released a video online in which it threatened to launch DoS attacks on Egyptian government Web sites if the authorities did not curtail censorship efforts. Earlier today, five people were arrested in the U.K. in connection with those attacks.
