blue security and prolexic knocked off by upstream attack

I have a ton of respect for Prolexic and what they offer to our world. But the spammers and botnets have waged a mini-war against Blue Security and anyone who seems to assist them. But instead of directly attacking Prolexic, a botnet was leveraged against upstream DNS servers for UltraDNS. Wow, just wow. This is the sort of cyberwarfare that is coming or already here where masses of zombied computers are wielded. So far much of this has been individual hackers or groups with personal beefs, but much like phishing and virus attacks, I expect things like this to take a much more organized and sinister turn in the next 4 years.
