This doesn't make sense to me. You're saying here that a 1% increase in average traffic is a 1% average increase in traffic. What's your point? if a load change is concentrated in one place how can the impact be global? How can a 1% load increase in one specific place have anything but minimal impact? At root and gTLD servers I assume DNS traffic occupies significantly more than 3% of all traffic there. Still, a 1% increase remains 1%. -- Niels.
