Hi Perry, What is involved and required to host an AMP node? If you could send me the details I can see what we can do on our end to locate on in a suitable part of the network.

After the discussion a few weeks back about DNS performance, I asked one of my colleagues, Brendon Jones to add DNS performance to the gTLD/Root servers to our Active Measurement Platform (AMP) which is already monitoring the .nz nameservers. These have now had a while to collect some data and show a fairly interesting (and IMHO pretty visualisation of New Zealands DNS performance)
I note that TelstraClear and Telecom aren't listed in these statistics as sources. Given that these are major ISPs (and they don't seem to peer at the NZIX exchanges :), have you any way of gathering statistics for their connectivity to either the .nz nameservers or the root/gTLD nameservers?
If you look closely at the traceroutes from many of the Universities (eg Waikato) you'll see that they use Telstra Clear as their upstream, although this is obviously imperfect as they also generally have KAREN connectivity. Unfortunately I don't think we have any visibility into Telecom's network.
What about other ISPS which don't have affiliation to either the NZIX exchanges or to one of the universities (and who aren't peering with them)?
Many of the "nsX" amp nodes are hosted at various ISPs (if you hover over them they give you a description that might be more useful), for example the AMP node called ns4a is hosted by Orcon. We're always interested in hosting more AMP boxes around the Internet (and particularly in New Zealand) to broaden what problems can be diagnosed by the AMP pages. For a variety of reasons, we provide the hardware and maintain the software build on the machines. Unfortunately we're funded by various grants, none of which at this moment cover buying new AMP machines. (But if people are willing to help with the costs, I'm sure we can arrange something). We generally try and put AMP boxes with cooperating sponsors, usually at points in the network where high performance use is expected, so AMP currently deliberately doesn't measure what end user DSL customers are likely to see. If anyone at Telecom or TelstraClear wants to host an AMP box to help diagnose routing issues between ISPs then get in touch and we'll see what we can organise. _______________________________________________ NZNOG mailing list NZNOG(a)list.waikato.ac.nz http://list.waikato.ac.nz/mailman/listinfo/nznog
