It's come to my attention that some of our worldwide slave nameservers are not updating when changes are made to the DNS on our master nameserver, 'ampr.org' (44.0.0.1).
It will take me a while to contact the operators of those nameservers to ensure that their configurations are correct for them to get the latest changes as they occur.
In the meantime, there may be differences in the answers you get regarding new entries in the DNS depending on which nameserver your query is actually made to.
The way to tell if a particular nameserver is current is to examine the serial number in the ampr.org SOA record as retrieved from it and compare that with the SOA from ampr.org (44.0.0.1). I use the 'dig' tool for this purpose; there are other tools as well. - Brian
Hey Brian,
Speaking of nameservers. How do we, as coordinators, update the zone respective to the allocations for our region?

Brian,
Here is a script you might find useful for diagnostics.
$ cat nssoa.sh #!/bin/bash ZONE=${1:-ampr.org} for nameserver in $(dig +short ns $ZONE); do echo "$(dig +short soa @$nameserver $ZONE | cut -d' ' -f3)" "$nameserver" done
$ ./nssoa.sh | sort 1708281715 ns0.comgw.net. 1708282030 munnari.OZ.AU. 1708282030 ns1.defaultroute.net. 1708291000 ampr-dns.in-berlin.de. 1708291800 ampr.org. 1708291800 ns2.threshinc.com.

Yes, that is very helpful. Thank you. - Brian

Unfortunately, that's based on the list of name servers in the authoritative zone file and not based on the list of servers in effect as set by the dot org registry.
I've expanded on Tom's script to take that into account and found there's apparently a couple of servers not answering at all.

A good source of diagnostic information is IntoDNS, and that shows a lot of problems with ampr.org:

Yes, I'm now aware that there are nameservice problems and I'm working on it. It won't be fixed quickly because it requires manual intervention by several people in many different places around the globe, including the registries.
Thanks all for bringing this to my attention. - Brian
