Well, doesn't really matter if you can resolve the A/AAAA/MX records, 
but you can't connect to the network that is hosting the services.

At any rate, having 3rd party DNS hosting for your domain is always a 
good thing to have. But in reality, it only hits the spot if the service 
is also available on a 3rd party network, otherwise, you keep DNS up, 
but get no service.
