The issue is my local recursive DNS servers will not resolve some domain names. In particular,
www.weather.gov. They will resolve most other .gov sites with no issue. During my investigation I tried using some open DNS sites. Most will resolve the query, but some of those have the same issue I have, no servers could be reached. I have gone through Red Hat support and they could find no issues with my configuration. I then used
www.dnsstuff.com to look up information on the domain in question. I can do a query against the listed nameservers and get a proper reply, however I can not get a reply from the primary nameserver. My question is in 2 parts. 1, is this my issue or theirs? And 2, is there a way for me to correct the issue? I have tried to contact weather.gov but got no response. Below is some details I got during testing. I believe what is happening is the primary is listed on the root servers for a place to get a reply. in my case it has the shortest RTT, so my servers try going there. The connection times out and so I can not get it to resolve. Any thoughts and ideas welcome.

Some open dns servers also time out while others will resolve.
