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?
