Error querying a.gtld.biz.

a.gtld.biz doesn't know about dss.state.la.us.  This is because 
"state.la.us." is delegated "away" and anything below it will be 
found on another server.

How about this - DiG gives a better "view" of the chain.:

$ dig +trace dss.state.la.us. ns

; <<>> DiG 9.4.1 <<>> +trace dss.state.la.us. ns
