UltraDNS who look after the TLD .info and soon the .org were hit badly at the end of last week. They reported that it wasnt a very large attack but it was enough to worry them and it realy tested their resources.
It was roughly a month ago that the root DNS servers took abit of a hammering with a DDOS and 7 out of the 13 were taken out of action for an hour.
Is this to be a regular thing, if so what is the future of the net, will all DNS servers live in fear of one day being so badly hit that the net grinds to holt, it would have to be a huge attack I know, but its not out of the question!
I'm not that DNS knowledgable, but i didn't notice any huge difference in the stability of traffic when 7 of 13 went down a month ago, i think we will see these articles more often in the future though.
I'm not a fountain of knowledge about DNS either, but when that attack went down I had a load of trouble in Asia. I couldn't access numerous sites in Europe and other areas. Queries even to WebmasterWorld took forever to load...it was like the old dial-up days, click a link, get some coffee, come back and if you're lucky the page has loaded. It was pretty bad. A number of sites looked like they had simply gone offline. I didn't get much work done.
