Re: Failure of secondaries

First off, ns1 and ns2 seem to have more than 1 A record, for no good
reason.  ns3 is ok.

[maze@nike ~]$ host ns1.resultsbydesign.com

Here's a query to ns2:

[maze@nike ~]$ host -v -t ns greenlightsport.com 216.253.111.180
Trying "greenlightsport.com"
;; connection timed out; no servers could be reached

and ns3:

[maze@nike ~]$ host -v -t ns greenlightsport.com 216.253.111.163
Trying "greenlightsport.com"
;; connection timed out; no servers could be reached

Either those servers are down/broken/misconfigured, or you've got a
firewall somewhere in there...
