> Hello Sir,
>
> Alex at Doubleclick asked us to work with you regarding this ticket.
>
> We have reason to believe that the reports you've received regarding
> these three machines being compromised 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 and intelligently directs
> requests
> to the best-suited Point of Presence (POP).
>
> In the course of determining the best suited POP, Global Dispatch preforms a
> 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
> preform this latency mesurment, and hope we have not caused you any
> inconvenience.
