Total speed check failure shouldn't be cached #1737

I am setting up a VPN (for IPv6) and noticed that resolution fails for domain X when none of the IP(v6)s is reachable. This alone does not make any practical difference, but when the IPs becomes pingable, the old result is still cached so the domain fails to resolve while it should. IMHO this is not a desired behavior.

I am on SmartDNS 45 and I apologize in advance if I missed the configuration option for this.

Old results will be cached until the ttl set by the domain owner has expired; empty results will be cached; no results will not be cached.

Maybe I don't understand. I hope you can give me an example.
