Yes, but besides the A servers, which they can tweak, you have another 12 classes of servers that are at the same root level. So, for example, can they access the DB of class K server which is in the Netherlands?<div><br></div>
<div>The update feature in the protocol propagates the changes in the DB and that eventually affects all the DB in all the DNS servers in the world.</div><div><br></div><div>So - this is possible because of their location and because of root server update algorithms.</div>
<div><br></div><div>If, by chance, the K server chose not to update*, users in Europe would still be able to find a US-canceled .com domain.</div><div><br></div><div>BR<br>NG</div><div><br></div><div>* this is fact impossible because the RFC that rules this states that it has to update.<br>
