I have no idea about Verisign's scheme, but in case anybody notices similar distribution of queries across F root servers, it may help to know that:
xxxNa.f.root-servers.org xxxNb.f.root-servers.org xxxNc.f.root-servers.org etc
are hosts all located at the same site "xxxN".
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.
