Our domain is hosted at Heroku, the registrar is Godaddy, the DNS is hosted at Godaddy.
The web services portion of our app had significant outages today+yesterday due to issues with Amazon AWS accessing DNS at Godaddy, eg, Godaddy DNS has been flaky, so Amazon-based services were seeing lots of errors when trying to resolve our domain name.
We'd like that NOT to happen again, so I'm trying to find out what (if any) secondary DNS services are compatible with having Godaddy as the primary DNS.
I have not found ANY of the other dns providers who state they can work as backup for DNS at Godaddy.
Any pointers on implementing a backup for DNS would be appreciated!
(It SEEMS like you can only get secondary or backup DNS form the SAME company that does your primary? At least for Zerigo and dyndns and easydns I don't see a standalone backup DNS option... doesnt that defeat the purpose of having a backup if the same company whose primary broken s handling the secondary?)
