<html><head><meta http-equiv="Content-Type" content="text/html charset=us-ascii"></head><body style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space;">I am having an issue resolving <span style="font-family: Menlo; font-size: 11px;"><a href="http://www.cloudsat.cira.colostate.edu">www.cloudsat.cira.colostate.edu</a> from 2 of my </span><font face="Menlo"><span style="font-size: 11px;">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?</span></font><div><font face="Menlo"><span style="font-size: 11px;"><br></span></font></div><div><div style="margin: 0px; font-size: 11px; font-family: Menlo;">dig <a href="http://www.cloudsat.cira.colostate.edu">www.cloudsat.cira.colostate.edu</a> @<a href="http://ns1.service.uci.edu">ns1.service.uci.edu</a></div><div style="margin: 0px; font-size: 11px; font-family: Menlo; min-height: 13px;"><br></div><div style="margin: 0px; font-size: 11px; font-family: Menlo;">; <<>> DiG 9.3.4-P1 <<>> <a href="http://www.cloudsat.cira.colostate.edu">www.cloudsat.cira.colostate.edu</a> @<a href="http://ns1.service.uci.edu">ns1.service.uci.edu</a></div><div style="margin: 0px; font-size: 11px; font-family: Menlo;">; (1 server found)</div><div style="margin: 0px; font-size: 11px; font-family: Menlo;">;; global options: printcmd</div><div style="margin: 0px; font-size: 11px; font-family: Menlo;">;; Got answer:</div><div style="margin: 0px; font-size: 11px; font-family: Menlo;">;; ->>HEADER<<- opcode: QUERY, status: SERVFAIL, id: 1057</div><div style="margin: 0px; font-size: 11px; font-family: Menlo;">;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 0</div><div style="margin: 0px; font-size: 11px; font-family: Menlo; min-height: 13px;"><br></div><div style="margin: 0px; font-size: 11px; font-family: Menlo;">;; QUESTION SECTION:</div><div style="margin: 0px; font-size: 11px; font-family: Menlo;">;<a href="http://www.cloudsat.cira.colostate.edu">www.cloudsat.cira.colostate.edu</a>.
