Re: Local root zone (Was NYTimes: Egypt Leaders Found ‘Off’ Switch for Internet)

[Fred Baker <fred () cisco com>]

I don't think that the Egyptian shutdown of domain names had much effect; that's why the bgp prefixes were withdrawn. 
What was effective was the withdrawal of BGP prefixes.

http://www.renesys.com/blog/2011/01/egypt-leaves-the-internet.shtml notes, for example, that routes *through* Egypt 
were operational, but routes through the same fiber and the same routers *to* Egypt were non-functional.

https://labs.ripe.net/Members/akvadrako/live_eqyptian_internet_incident_analysis pretty clearly states that "prefixes 
associated with Egyptian ISPs were withdrawn".
