I once achieved something similar with PowerDNS, which you can use LUA rules to do health checks on a pool of servers and only return health servers as part of the DNS record, but found odd occurrences of clients not respecting the TTL on DNS records and caching too long.
- tetha 2y agoYou usually do this with servers that should be rock-solid and stateless. HAProxy, Traefik, F5. That way, you can pull the DNS record for maintenance 24 - 48 hours in advance. If something overrides DNS TTLs that much, there is probably some reason.
