From my perspective, blogchina.org has 12 authoritative name servers (as reported by a0.org.afilias-nst.info). ns1.dnspod.net. ns1.qydns1.com. ns2.qyinc.cn. ns1.qydns2.com. q3y1dns1.mydnspod.com. ns6.dnspod.net. ns1.qyinc.cn. ns4.dnspod.net. ns3.dnspod.net. ns2.dnspod.net. q3y1dns2.mydnspod.com. ns5.dnspod.net. If I request the NS records for blogchina.org there, none of them gives an answer section; some (ns1.qydns1.com, ns2.qyinc.cn, ns1,qydns2.com) even time out without any response. Start by checking: * if these are the correct servers? if not, you need to change them via your registrar * if these servers are configured to server your zone? most of them return a SOA, so they seem to know about it * if these servers have correct zone data? none of them returns NS records Greets, Niobos ___ bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users

You're saying its getting the records because they are cached at org? -Original Message- From: bind-users-bounces+jlightner=water@lists.isc.org [mailto:bind-users-bounces+jlightner=water@lists.isc.org] On Behalf Of Mark Andrews Sent: Friday, October 15, 2010 9:21 AM To: Tech W.
