OK, I understand. So, like Elmar Bins, I was seeing "intra-site"
jitter, which is normal (it is only seen with UDP queries, probably
because the Verisign load balancer is stateful and remembers the
binding for TCP) and no "inter-site" jitter, which would be more
serious. But I'm quite at this edge of the Internet, so let's wait for
more reports with Peter Boothe's tool. And just be sure to "sanitize"
the results before jumping to the wrong conclusion, like I did.
