Yes, please read ISC's tech note on this:

http://www.isc.org/index.pl?/pubs/tn/ (select ISC-TN-2003-1)



which talks about ISC's F-Root operations.

In short, most of our nodes are considered "local nodes" where the local 
F-Root server is made available to those that peer at the local IX where 
we are located at.  So if a ISP is able to peer with us at any of our 
locations, we will be happy to set up a perring session and their 
customers will reap the benefits.  Otherwise the F-Root traffic hits one 
of our "global nodes", which is what you saw with your dig query.
