Hi.

I've been debugging DNS nslookup failures on my home PC and found that a tracert output showed an unusually long delay for one of the hops.

C:\>tracert 202.27.158.40

Tracing route to dnsc1.xtra.co.nz [202.27.158.40]
over a maximum of 30 hops:

  1     9 ms     2 ms     1 ms  10.10.2.1
  2    14 ms    13 ms    16 ms  219-89-48-1.dialup.xtra.co.nz [219.89.48.1]
  3  1455 ms  1693 ms  1303 ms  mdr-fid-dom.akcr10.global-gateway.net.nz [202.50.238.50]
  4     *       12 ms    14 ms  ae4-20.akcr10.global-gateway.net.nz [202.50.238.49]
  5    13 ms    13 ms    13 ms  v4.aksw7.global-gateway.net.nz [210.55.202.51]
  6    13 ms    13 ms     *     xtra-dom-1.aksw7.global-gateway.net.nz [203.96.120.146]

This is from a ADSL2+ connection using a static IP in Auckland 125.236.215.xxx, broadband Pro connection, so internet connectivity should be quite good and unlikely be the cause of the delay.

Connections to remote locations in Africa don't have such large delays.
Is there some problem with the Xtra DNS routing or is it simply an anomaly with the tracert?

Nothing looking wrong with that. What DNS servers are you using - standard Telecom DSL ones?

Not just you, mdr-fid-dom.akcr10.global-gateway.net.nz [202.50.238.50] is responding VERY slow for me too. 1200-1500 ms! And thats routing to telecom.co.nz

That's unusually high latency, I'm seeing the same.

The easiest ways to report this issue to Telecom are via the "email us" link on http://www.telecom.co.nz/contact or their Twitter account http://twitter.com/#!/telecomnz

If the response times from the subsequent hops are normal, as they are in the original post, then it's normal router behavior - thus nothing to report.
