Hi There,

I can get someone to take a look into this, or at least contact you.
They may very well ask you to do some traces using dig to see what is going on.

Sebastian is correct there are load balancers in the mix.

I would suspect that you are correct, one or more of the servers may have an issue.

Do you get any other failures for signed zones?

Paul

We have solid evidence to show that there is a load balancer in front of
the IP Spark uses for resolver.

Having now got access to a resolver in an Xtra network, there definitely seems to be an issue, I can attempt 10 queries of the same host and get (randomly) 7 successes and 3 failures.

The Recursive farm would appear to have at least 8 members, rns1-8.xtra.co.nz, I have the IP addresses of 4 of them (tcpdump :)

So at this stage my guess is one of them is not so healthy. But I still can���t find a communication channel to discuss the situation with anyone at Xtra :-(
