CloudDNS is a cheap DNS hosting solution with a 100% uptime SLA and provided by Google.
Is it free?
Free, no, cheap, yes https://cloud.google.com/dns/pricing
Its also free if you use the google domains service
This would be a great addition. I use the dns for my own sites (3, very little traffic) every 6 months or so I need to pay them 80 cents or so... I have a client with a few hundred domains and its not much more expensive. I will take a stab at adding this option to the code today.
I would think the best way to use this would be to build the wrapper around the google's gcloud tool rather than implement the API access to google cloud dns
Abandoning ticket.
