Absolutely.

My question exactly, already stated in this very thread, I think <smile>.

The only thing I can think of is that perhaps you didn't update the serial, 
and your old TTL was five days, and one person from @Home happened to read 
your DNS the moment your primary was down, and got your secondary?  Or 
maybe your TTL was correct, but five people did it over a period of five 
days?  I DON'T THINK SO <wry grin>.

Your guess is as good as mine <smile>.

Cricket Liu, one of the authors of "DNS and BIND" can be hired, for some 
awfully huge some of hundreds of dollars an hour (or so I've been 
told).  I'm sure he could figure it out.  Is it worth it?  Maybe if 
amazon.com or ebay.com has to renumber, it might be, but to me, frankly, NO 
<smile>.
