DDOS campaign against DNS

Anonymous has posted a warning that it will shut down the web in "Operation Global Blackout", which claims that the Anons are going to test the limits of their distributed denial of service attacking capabilities at the end of March.
The DDOS campaign is expected to target the world's 13 domain name servers (DNSs). If the attack indeed materializes and if the DNS servers are all taken down, the internet could be shut down. According to the outfit by cutting off the Internet, nobody will be able to perform a domain name lookup, thus, disabling the HTTP Internet, which is, after all, the most widely used function of the Web.
Anybody entering "http://www.google.com" or ANY other url, will get an error page, thus, they will think the Internet is down, which is close enough. "Remember, this is a protest, we are not trying to 'kill' the Internet, we are only temporarily shutting it down where it hurts the most." In other words "we're not trying to kill the internet, but we're trying to kill it for a little bit," Anonymous said.
The tool they will use is the Reflective DNS Amplification DDoS tool. By spoofing the DNS server with UDP packets, the attacker tricks the DNS server into sending messages to itself creating a cascade of failures. The sent packets are small, but they trigger a large barrage of data.
We doubt it would work, and if it does it would create a huge backlash against the outfit with governments calling for more powers to clamp down on them.
