Renesys visualizes the Egyptian Internet Outage

March 21, 2011  »  VideoOne Comment

Renesys Corp recently uploaded a visualization of January’s Egyptian Internet outage. In the description, the company wrote:

It [The video] shows the routed address space for each country, colored by reachability (at the routing/BGP level). Space in green is globally reachable, while space in red has had all covering routes withdrawn. You can clearly see the departure of the vast majority of Egyptian address space after the government-ordered shutdown, and the return of the Egyptian space about a week later.

The interruptions in service visible in Saudi Arabia and in Iran are interesting, but most likely unrelated.
