RE: UUNet Offer New Protection Against DDoS

  • From: Lumenello, Jason
  • Date: Wed Mar 03 16:24:34 2004

XO set up a similar customer community last year for our customers to
trigger their own black hole at our edge. There is no such thing as an
original idea. :) This "promised response" probably means if you press 3
on your phone, you will get a CSR to open a ticket within 15 minutes.
Sounds like nice marketing.
