It's not your job to second-guess them. There are some servers that will avoid expiring records if the auth servers stop responding, as a fail-safe mechanism. I think Google Public DNS does this. So they obey TTL when deciding when to try to refresh the cache, but will continue returning whatever they've cached if necessary. -- Barry Margolin Arlington, MA _______________________________________________ Please visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list bind-users mailing list [email protected] https://lists.isc.org/mailman/listinfo/bind-users
