No major DNS provider would engage in a "Selective DNS Blackout" because of resource constraints - DNS is one of those protocols that is both embarrassingly parallel, as well as super efficient to serve. It's not unreasonable to see a well tuned, inexpensive (< $5K) DNS server provide on the order of 100,000 responses/second. And if you want to serve a million responses/second - just scale horizontally and add the resolvers to your VIP pool on your load balancer.
This article doesn't pass the common sense test. Not to say that GoDaddy isn't engaging in this selective DNS blackout policy, just that it's not because of a underinvestment in their infrastructure.
That makes a lot more sense. It would be a lot better if the DNS provider said something like, "First million DNS entries served is free, after that, we charge you $0.50/million queries" (Amazon pricing for DNS)
Then, you respond to every request as fast as you can. (Note, this also provides an incentive to the customer to jack up the TTL on the resource records, so 99.99% of the requests are handled at the caching servers instead of GoDaddy)
Some proof would be nice here. I almost thought having some proof after using Watchmouse DNS Analysis on a Godaddy DNS hosted domain: http://www.watchmouse.com/en/dnstool.php?varghost=cheapdomai... , and hit some 'No response' from multiple locations. But some Watchmouse test locations always reply with 'No response' (Amsterdam3-Netherlands; Belgrade-Serbia; Budapest-Hungary; Frankfurt-Germany; Lille-France; Madrid-Spain; Novosibirsk-Russia; San Francisco-U.S.A.; Sofia-Bulgaria).
Any other good DNS tool that queries from multiple GEO locations?

Maybe the article has been changed but it indeed says that it most likely not about cost but about pushing a 'premium' dns service.

The company that uses bikini-clad women gyrating on the screen as advertising may not be very professional with their IT infrastructure? Who knew!
Seriously, time to migrate to namecheap.com or other. Its sad this kind of advertising even works.
