Why doesn't bind query the second DNS?

[Leonard den Ottolander]

Hi folks,

 Thanks a lot for your answers.
 No, I am not in any way responsible for these DNS's. The question was just 
out of curiosity.

 This is good to know. Guess I should read up on this a little bit. Any 
suggestions (books, online resources)?
 I feel a bit silly that I oversaw the fact that the two yoho.com DNS's are 
actually the same machine. It definitely explains why no servers could be 
reached. Next time I'll look a little closer before asking. It's just that 
lately I had some trouble with the resolving of another name. This problem 
(almost totally) dissappeared after upgrading from bind-8 to bind-9. Not sure 
if that is coincidence. If I encounter that problem again I might bother you 
with some more output :).

Thanks again,
Leonard.
