Early observations of the TCP attack volume from a few of our datacenters indicate packet flow bursts 40 to 50 times higher than normal. This magnitude does not take into account a significant portion of traffic that never reached Dyn due to our own mitigation efforts as well as the mitigation of upstream providers. There have been some reports of a magnitude in the 1.2 Tbps range; at this time we are unable to verify that claim

Holy shit, 1.2 Tbps? That would make this one of the largest DDoS attacks ever right?.
