There are stats but we do not have a view on the exact numbers of people
who have configured alien and terminator as their DNS. There will be
some and they will be impacted in some way from recursion being
disabled.
Hence the heads up.

"no answers" is the usual "not here" reply (like ns1.ihug.co.nz)
And therein lies the problem.
For a non Xtra user, that has Xtra DNS servers hard coded, 90% of DNS
requests will probably work because Xtra's servers have much of the nz
internet namespace in their cache, (or the servers are authorititive)
The IP address 202.27.184.3 is a virus, it seems have spread into the
configurations of many NZ computers, I think it is one of those "it just
works" scenarios and computer technicians have used it as a default fix
for
many "wierd" DNS issues.
Once Xtra disable recursion for non Xtra customers, those same
techncians
will be challenged with trying to diagnose a very intermittent "page can
not
be displayed" fault.
Ted, if we assume this change is being made because there are a
significant
number of requests (relative to the size of your user base) coming from
non
Xtra IP addresses, then we would have to assume that a significant
number of
users (that have dumb client resolvers) are going to be affected.
Are there any statistics available from your name servers on the scale
of
this issue (Like is it 10% non Xtra requests?)
Cheers
BG
All IP's mentioned in my previous email are still accepting queries.
Nothing has yet been implemented as we wanted to ensure advance notice
was given so I'm not sure why you were getting 440's sorry.

Most likely your option 3 Brian. There can be expected that there will
be some customers who'se interweb thingy appears to die on them. Hence
our advance notice.

What action will those servers take when they receive a request from a

Will they :
1. Quietly discard the request (as in, blocked by a front end firewall)
2. Return a referal to another DNS server e.g. .co.nz etc.
3. Return "invalid domain name"

Dear Colleague,
This is to notify you that some object(s) in NZRR database
which you either maintain or are listed as to-be-notified have
been added, deleted or changed.
These objects are used to configure the various NZIX route
servers (http://nzix.net/) so you can expect the relevant
servers to be reloaded in the near future. The reloading
of the servers is staggered over a period of time so that
if you are peering with both servers at an exchange, you
can maintain at least one BGP session at all times and
consequently a full set of routes.
