OTOH, I can believe that somebody broke a Perl script critical to it and it rolled out a valid, but empty, zonefile which the secondaries faithfully replicated. Not that I've watched cascading DNS failures at too many places with bits of crufty Perl, oh no...
ISTR some database extract failing in a new and unusual way a few years ago, and about 1/3 of the entire .com domain evaporolated for several hours....
This is an old, old story -- such failures have been with us for a long time. Not all that many years ago, the entire (US) 800 number system was down for a similar reason -- the program that populated the production database from the back end master copies hiccupped, and things got *very* confused.
