The policy that caused so much pain before is to take DNS records, ignore their TTLs, and apply some other arbitrarily selected policy instead. I confess, I don't understand how the proposal at hand is different in ways that prevent the previous pains from recurring. Maybe you can enlighten me on key differences I've overlooked? How do you define "failing to reply"? Do you ever stop serving records for being stale, or do you store them indefinitely?
