We know this isn't good engineering practice, because another national ISP with millions of subscribers configured their network the same way, and experienced a multi-hour service disruption affecting most of their users a couple of years ago when an error blocked access to their two caching-only, name servers.
You mean there are national ISPs out there, who have exactly 2 caching nameservers, as opposed to configure their clients with 2 IP addresses (perhaps always the same 2) which perform name resolution? Wow. Is this some sort of retro fashion? -- Alex Bligh Personal Capacity
