Can you say more about the benefit of this "zonelet" system vs. ARIN 
simply delegating the appropriate zones to you, and you managing them 
like any other DNS zone?

I do appreciate you keeping the community informed about the causes of 
the outage, but it seems that at least part of the root cause is that 
you're operating what sounds like a fairly fragile system in the first 
place, with (de fact) insufficient validity checking.
