Thank you, Tony. You're right.
I do see a difference in behavior when querying other authoritative,
non-AWS servers. I didn't realize it was the job of the authoritative
server to do the math and present the proper ttl. Thanks for the
pointer to the relevant section in the rfc.

Given this soa:
fe80.info. 3600 IN SOA ns-538.awsdns-03.net.
awsdns-hostmaster.amazon.com. 1 7200 900 1209600 60
I see bind caching negative answers for 3600 instead of 60. The rfc
and my google searches suggest that it should pick the MIN(soa ttl,
soa min ttl) for that purpose. What am I missing
