I am having an issue resolving www.cloudsat.cira.colostate.edu from 2 of my name servers. I have 2 others with identical configs that resolve correctly. A normal lookup shows a server fail but a +trace looks ok. Any ideas how to better troubleshoot the issue?
dig www.cloudsat.cira.colostate.edu @ns1.service.uci.edu
