Some say DoS, some say protected.  If someone is trying to poison my DNS
Cache I'd rather ignore them and blackhole than accept their attack and
go to the wrong place.  Besides, DNS allows me to go ask multiple
sources for information.

If I'm expecting a DNSSEC response and don't get it, I know that I need
to go ask somewhere else.  That's a FEATURE, not a bug.

If I'm sitting in a hotel room behind a broken middleware box then I
know, for sure, that the middleware is breaking me; I can turn off
validation at that point (or decide never to stay at that hotel again --
or both!)

I have no idea what the DigiNotar security practices were.  I *DO* know
exactly what ICANN's practices are (and I even know at least one
key-holder personally).
