This appears to be the earliest "source" of the quote. http://forums.military.com/1/OpenTopic?a=tpc&s=78919038&f=409192893&m=4551982416 F-Secure has also been also been widely quoted with the same statistic. Since several root servers disabled ICMP after the last attack, I think they mis-read the ping loss as servers being down. 5 root servers never respond to ICMP. I did DNS queries of all of the root servers several times throughout the event. Other than G, I was eventually able to get responses from all of them. Sometimes it took several seconds to get a response. Folks have reported they were able to reach servers through particular networks, but not through other networks. For example, a person sent me data showing they could reach G through MFN, although I couldn't reach it through several other networks. I don't have a network connection on MFN.
