I know that this has been brought up at length recently. My apologies if
this is redundant, or has already been covered. The following excerpt is
snipped from a message one of my colleagues received recently in response
to our questions...

=========================================================================
We have reason to believe that the reports you've submitted
is a misunderstanding as a result of our enterprise traffic management
software: Global Dispatch.
Global Dispatch is a WAN-based scheduler that makes it easy to place
content
close to geographically dispersed users and intelligently directs requests
to the best-suited Point of Presence (POP).
In the course of determining the best suited POP, Global Dispatch performs
a latency measurement. This latency measurement is done by making a
connection
latency measurement. This latency measurement is done by making a
connection
to the client DNS server on TCP port 7 and then dropping the connection.
After
the latency measurement has been done, the latency values are cached, and
the
IP of the most responsive POP is returned to the requesting machine.
I hope this help clear up the confusion. We are looking into other ways to
perform this latency measurement, and hope we have not caused you any
inconvenience.
