Note that it may not be a conscious choice by the probe's DNS resolver operator: it could be hijacking. For instance, probe 32001 gets an answer from the root name server B in 3 ms, while traceroute shows a correct delay (B-root is only in the USA). And this answer is for the OpenNIC root, so this answer is certainly not from the real B-root. (This operator, AS 23860, does other funny things.)
