Do you know how many Gigabits per second it was?

  It was enough to take out anyone else who shared the same facility (like us...) and seems to have hammered the Layered Tech border routers into oblivion for 5-10 minutes, so I am guessing it was pretty big.

    Do you know if you have any DDoS mitigation devices in front of the border routers? Something from like Arbor Networks or Intruguard? In a few attack scenarios, it really helps. We're also facing a multi-gigabit attack this week and have dealt with some in the past. Happy to compare notes if you'd like: david@weebly.com.

      I should probably know this info but managed to forget it since the site I run has to be placed outside these devices (our everyday traffic is almost indistinguishable from a DDoS.) In fact, that might tell you something, since our Chicago data center was taken out as collateral damage and we sit in front of these devices if you were to draw a big-picture network diagram of the site. From what I can tell so far the attack was just melting the uplinks and it took a few minutes to null-route the various attackers; when things got fixed they did so on specific routes (e.g. Layer3 to the east coast came back before another route the Dallas and the southeast, etc.)
