I'd point out that FastFlux is actually sort of how Akamai does it's job (inconsistent dns responses)
That's not really fast flux. FF uses TTLs of just a few seconds with dozens of NS. Also, in practice, most FF NS are invalid. Not that FF has a fixed definition...

akamai, 60 second TTL's... most of the FF things I've seen sit around 300seconds for NS and for A records. either way, this is 60 seconds which is fast enough.
Interesting, I was under the impression anything less than 120 is effectively as good as 120.
I have not measured... I bet yahoo has though :) and/or Akamai. There's a reason that these folks are doing this. Would be an interesting presentation though eh? -Chris
