DRP server startup

[Friesen, Don MTIC:EX]

  No.  The log shows it receiving nothing.  The prod servers log a lot of inbound traffic, and any offers they make.  This server logged nothing at all.  Which I find odd.

Perhaps, because it is at a far away site the reply from the server took much longer to get back to the client and the client therefore selected one of the closer servers?

I wouldn't like to rely on this behaviour though, so best to configure it properly :)
