They are, but they are not even using the amount of redundancy available
by DNS today (read: "as many name servers as fit into a minimum sized
UDP packet full of glue").  So there is hardly an argument for doing
anycast.

The route servers use TCP, which will not work over anycast (in the
general case - consider load balancing, every other packet going to 
a different destination machine.  No problem for UDP, big problem
for TCP)
