The root servers were attacked this morning. My guess would be few (if any) really felt the effects. This just goes to show that the net, despite being a distributed mess of networks still has a few critical points in its infrastructure. They didn’t take them down, and didn’t even get them all. Here’s a creepy graph. For the record there are more than just the physical A-M servers. C,F, I-K, M are using anycast so they are distributed among many networks, making it even more redundant, and closer to most users. Because it was done by a botnet, and all but one of the targets were using anycast (according to Wikipedia), the load would be distributed across the servers, making it even harder for an attack to succeed.
