Can someone explain the impact of widely-distributed fiber on DDOS attacks? As I understand it, if 1-2 of these nodes get compromised, then add in the 10-100x magnification via DNS, you're looking at 10-100gigabits of bandwidth off only two nodes? Compared to the recently published high of 300, this seems disproportionally high.
That said, a botnet host running on this network would be substantially more capable of causing damage than a host on an 8Mbps upstream.
Hopefully google has plans or already has implemented some ability to mitigate that type of problem...
