Sprint security contact

One of our customers is currently undergoing a ~30Mbs DDoS to a single IP. We've BGP blackholed them within our network, but they are still beating up on our upstream links. UUNET has blocked them internally, but I'm getting bounced around within Sprint to have their NOC/security group work on it. I started with our contact information and also the puck.nether.net info. If there is a Sprint security person on list, please contact me. If somebody has a direct Sprint NOC/Security contact, please pass it along. Thanks, Rick
