You solve this by having more than one domain controller running DNS in your environment. A domain-joined client should use only domain controllers for DNS.
From your router (or whatever is handling DNS resolution), you can delegate queries for ad-related names, say all Those for the ad.example.com domain, to your domain controllers. This would allow non-ad related names to still be resolved even if the domain controllers are down.
