FYI - looks like there is an issue with telecom authoritative DNS.
Short version: it's currently broken.
Long version: there is a whois/NS loop
$ whois telecom.co.nz http://telecom.co.nz. ... domain_datelastmodified: 2014-07-28T13:54:33+12:00 ... ns_name_01: ns1.spark.co.nz http://ns1.spark.co.nz ns_name_02: ns2.spark.co.nz http://ns2.spark.co.nz ns_name_03: ns3.spark.co.nz http://ns3.spark.co.nz
$ whois spark.co.nz http://spark.co.nz ... domain_datelastmodified: 2014-06-10T10:08:28+12:00 ... ns_name_01: ish4.telecom.co.nz http://ish4.telecom.co.nz ns_name_02: ish5.telecom.co.nz http://ish5.telecom.co.nz
No glue records, so no way to resolve the NS IP's
Just to add some details, the problem is related to the cyclic dependency between telecom.co.nz and spark.co.nz. When a cache tries to resolver telecom.co.nz, because the absence of glue records in the parent zone (co.nz), it will try to resolve spark.co.nz, which to be completed needs to resolve telecom.co.nz. Without a hint, there is no way to bootstrap the resolution process, so it fails. It's up to Telecom to have it fixed, hopefully it will be done sometime soon. Cheers,
FYI: ish4.telecom.co.nz http://ish4.telecom.co.nz. A 146.171.13.195 ish5.telecom.co.nz http://ish5.telecom.co.nz. A 146.171.13.194
ns1.spark.co.nz http://ns1.spark.co.nz. A 146.171.13.195 ns2.spark.co.nz http://ns2.spark.co.nz. A 146.171.247.25 ns3.spark.co.nz http://ns3.spark.co.nz. A 146.171.13.194
