[isp-dns] Re: Should I have to restart BIND for updates?
You don't really have much control over how long a 'positive authoritative' response is cached. That's determined by the TTL and/or SOA values for the other domain. Thats why we always tell customers it will take atleast 48 hours for changes to show, and in some cases upwards of a week.

would I even have known, had one customer not been trying to access the

I think something was wrong.  Perhaps I am just a pessimist.
