Hackers make bunny cry. - Image 1QJ may have seemed down all day, but we were hard at work churning out the latest (and not-so-latest) news this side of the afterlife. When Joecool mentioned something about DNS attacks, we were all on the alert.

As Joecool mentioned on our comments for the downtime:

Not to mention today (rather yesterday now that i'm saying this), there was a huge attack on 3 out of 13 of the root DNS servers that run the internet, the largest global internet attack since 2002.


A little digging confirms his story. Apparently, three of the world's 13 computers responsible for managing a lot of the world's internet traffic was assailed by hackers for around 12 hours, one of the biggest attacks on the net since 2002. As Yahoo mentions,


The attacks appeared to target UltraDNS, the company that operates servers managing traffic for Web sites ending in "org" and some other suffixes, experts said. Officials with NeuStar Inc., which owns UltraDNS, confirmed only that it had observed an unusual increase in traffic.


Among the targeted "root" servers that manage global Internet traffic were ones operated by the Defense Department and the Internet's primary oversight body.


Well folks, now you know. If anyone knows who hacked the net, send them a prompt email asking them to stop. You made many World of Warcraft players around the world (and a few million Korean Starcraft players) cry.

Domain name servers DO NOT manage internet traffic. They merely translate domain names to IP addresses so that the browser knows where to connect to. Besides DNS root attacks are more or less useless because noone uses the root DNSs anyway. They are only used once an entry expires and thus is not available in the cache of other DNSs that are used by users (mostly those of providers).

The only thing it really affects are new domains that are not cached already and DNSs have to ask the root servers who manages the domain and which DNS has the information. So in fact the vast majority of sites are not affected by this. They may of course but it's quite unlikely.
