Testing has begun that will allow clearing firm networks to access the CME�s IP addresses for our mainframe and FTP servers located at the Remote Data Center (RDC).  Testing began June 16^th and continues through July 26^th.   Then we will host a clearing cycle test on two Saturdays in August.

 Testing to our RDC is mandatory.  Failure to comply can result in sanctions by the CME Clearing House.  In addition, in the event that the CME must failover to this remote location, firms who have not set-up and tested access out to RDC will not have the means to communicate with the CME.
