100% they will try again, they’ll just be a bit more quiet about, maybe do it once integrity feature at a time.

Yes there are a number of solutions out there including running your own bind server. But that is probably a little more difficult than what you might actually want which is just to consolidate their name servers down to one centralized place. Another comment mentioned one, clouddns is another that does this, maybe slightly differently?

Agreed, I do not like them, just adds lots of empty posts with little interaction.
