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 :-( -- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Glen Eustace, GodZone Internet Services, a division of AGRE Enterprises Ltd., P.O.
