Not even a little bit, the whole thing was written by someone who has no idea how the internet works. Even if they somehow managed to get all 13 DNS root servers offline at once, most people would never notice since there are several layers of caching between you and the root DNS servers. The vast majority of DNS queries never hit the root servers.

The whole time I was reading this article I was thinking exactly that: with the amount of caching present, no one would even notice.

Considering the fact that they don't understand this basic principle, I doubt they'll come close to taking down 13 DNS servers at once. You can't easily DDoS them (I'm guessing its the only tool they have in their toolbelts).
