Is anybody else seeing a routing problem making various NZ sites inacessible (including Geekzone, I'm on 3G at the moment to type this)? Hoon Hay in Christchurch. Tried ringing te help desk but estimated wait time was nearly an hour! Been like this since at least 1pm, probably earlier. The traces look like they try to leave NZ and get no further.

I called the "help" desk, I shouldn't have bothered: http://www.geekzone.co.nz/sleemanj

freitasm: This is probably the same problem reported here.

Unlikely... The problem reported in the other post is an HTTP Redirect, which isn't likely to be a redirect, it seems like HTTP Proxy cache is dishing up the wrong page to I.P DNS Request, this problem seems to be a geniune route problem, but it would be hard to tell, as some routers do not allow forward of traceroutes. BGP routes go wrong all the time anyway, its when they don't find another one problems start to begin.

Yep. Me to :-).
Complained with their custhelp thingy yesterday morning and got a reply today saying that it had been "forwarded to our technical support team".

I had a bit of a play during the day after that and discovered that packets were getting to their destinations from my cable connection but not the other way around. Packets heading for my cable connection stopped at 218.101.61.189. (I updated the custhelp thingy with this information last night). So I had my VPN between home and work (which for some reason stayed up, even though traffic was only working in one direction) sending traffic from home direct to work, but the other way I routed via a server I have in Florida :-).

Anyway, seems to be working now. Will have to be nice to them and tell them that (now going to 218.101.61.173 instead of 218.101.61.189).

Yea I guess it was just our subnet. Interestingly ICMP still not getting back to me, but obviously the trans proxy is ok..

Mate there are likely to be firewalls there.... Thats the only reason you can't traceroute past that host.
