Hi Folks, All this talk today about outages and the like had me looking at something I know about that I'm not sure everyone else is aware of but nevertheless is fairly awesome. H/T to the lads and ladettes at WAND. http://erg.wand.net.nz/amp/matrix.php/ipv4/latency/NZ/ If there were more nodes in the system we'd all get a better idea of what parts of NZ's internet are affected in times of trouble. Enjoy. jamie
That is so cool Jamie, thanks for posting it. I didn't know about it. It's going straight to the pool room [1] D [1] Movie buffs will get it :) On 8/04/2011 8:23 p.m., jamie baddeley wrote:

Hi guys I have a problem in my Christchurch network which is way beyond my ability and I need some help. The network uses Cisco, Trango and Mikrotik hardware and I'm a Mikrotik noob so I suspect that may be where the problem lies. I'm happy to pay the going network genius rate, this is worth more to me than beer ;-) If you can help, cantact me off-list. Cheers Stan
Hi Guys Thanks for all the replies, hopefully we'll have it solved shortly.

There's actually no L-Root server in New Zealand right now -- I suspect that Auckland University is seeing one of the instances hosted by AARNET in Australia. I'm guessing, though, since I don't have a test point to see directly. dig -4 @l.root-servers.net hostname.bind ch txt dig -6 @l.root-servers.net hostname.bind ch txt or dig -4 @l.root-servers.net . soa +nsid dig -6 @l.root-servers.net . soa +nsid ought to reveal a hostname, if anybody is interested in checking.

25ms seems like the right time for packets RTT between Auckland and Sydney.

Auckland, like most NZ universities uses BGP to prefer routes learned from the NZ NREN (KAREN) as the traffic is free. The issue is therefore that KAREN doesn't have connectivity to the root servers inside NZ. If Karen goes down, Auckland should start using NZ based root servers, but I don't think that has happened recently. I understand that KAREN are working on improving their DNS service. We currently record instance names for the .nz DNS servers. We will have a look at adding those for the roots. Richard. On 17/04/11 13:35, Gaurab Raj Upadhaya wrote:

I'm not sure your failover scenario is that likely as it would only work if Auckland had a working connection to the APE. Some manipulation of the routes received from BGP could prefer APE routes for the root nameserver prefixes ahead of the KAREN ones and have the failover work the other way which seems more sensible, And KAREN could improve their DNS service if they had connectivity to the Exchanges to access both root and .nz servers.
