DoS attack on DNS servers

I am sure everyone has heard about this but I was pretty shocked for a couple of reasons.

1. For the first time that I can remember a IT Security story was the lead story on news.com.au

2. The following story has one of the *best* analogies I have come across:

And I quote:

"A denial-of-service attack like this swamps web-connected servers with traffic from many computers around the globe. It's a bit like 20 hippos trying to get through a revolving door at the same time - there's no route through and everything clogs up."
