"Nice web site you got there friend. It'd be a shame if somebody DDoS'd 
you off the 'net."

As has happened.

DDoS rates above 300 GBps have happened.

One DDoS I worked involving OpenVMS. That DDoS clobbered network 
traffic. The DDoS traffic was using NTP reflection bug within OpenVMS. 
That NTP bug got fixed a while back. In this case, the folks weren't 
even targeting OpenVMS itself, just a flaw in OpenVMS, and their use of 
that flaw knocked access to a crawl. They weren't even ransoming 
OpenVMS network access, OpenVMS itself was "participating" in the DDoS 
of somebody else to the extent of its internet connection.
