AFAIK, authoritative slave servers are only used when the master is confirmed to be down. Lookups take significantly longer in such cases since for every request, the master will be asked first. This can take between 2-4s. There are no performance benefits to running multiple name servers as master-slave, though it's fairly easy and offers good redundancy (a slow lookup is still better than no lookup). A commercial service will have to support zone transfer from your master, and said master has to have that commercial service authorized to pull your zone(s). I haven't personally heard of such services, and would probably just run another BIND box somewhere else (different hosting provider or something like that). -- Michael De Roover <i...@nixmagic.com> _______________________________________________ Please visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list ISC funds the development of this software with paid support subscriptions.
