2) The Domainz RFI for the management of the DNS indicates that in the near future the primary and secondary servers will be operated by Domainz.

Hmm.
If we cast our minds back a while, we should remember that the reason CLEAR Net are running nameservers was that at the time all domestic authoritative nameservers were advertised globally by Telecom only.
A prolonged network problem at Telecom (well, Netway at the time, I think) resulted in the overseas authoritative servers being unable to refresh their copies of the zones, and the entire nz TLD effectively disappeared for a day. This had an impact on CLEAR customers, despite the fact that CLEAR had experienced no network problems.
I would suggest there is _strong_ operational motivation to colocate authoritative servers with different providers who have different international connectivity.
The current domestic authoritative nameservers obtain global connectivity as follows:
dns1.clear.net.nz via CLIX (by way of Concentric/C&W) dns2.clear.net.nz via CLIX (by way of Concentric/C&W) gorgon.xtra.co.nz via NetGate (by way of BBN/SprintLink) rata.vuw.ac.nz via NetLink (by way of Telstra NZ, by way of Telstra, by way of MCI/AT&T) ns99.waikato.ac.nz via NetGate (by way of BBN/SpringLink)
This shows some reasonable diversity. It would be a step backwards if this diversity was significantly reduced.
And I'm not for one moment suggesting that this should or will change. What I am suggestiing is that it's likely we'll see something like: ns1.domainz.net.nz via CLIX (by way of Concentric/C&W) ns2.domainz.net.nz via CLIX (by way of Concentric/C&W) ns3.domainz.net.nz via NetGate (by way of BBN/SprintLink) ns4.domainz.net.nz via NetLink (by way of Telstra NZ, by way of Telstra, by way of MCI/AT&T) ns5.domainz.net.nz via NetGate (by way of BBN/SpringLink) These names and locations are for example only. The connections points will need discussion and agreement from the major providers. --------- To unsubscribe from nznog, send email to majordomo(a)list.waikato.ac.nz where the body of your message reads: unsubscribe nznog
