Tangential, but makes me think: could all those happy campers who like to DDoS GitHub and Freenode in their spare time target an ad bidding node instead? I'd love to see that happen. Do it for teh good old-school lulz.
Hum... I just thought that we rarely see here a tech showdown from ad companies, or employees (It might be because they'd
be bullied to hell), for what we know they could have the most impressive anti-DDoS tech in the world.
