CME will be performing some tests today after the close of trading.  These tests will not begin until after the End of Official Transmission message is sent.  All test information will have the appropriate test message indicators.  However, it is not necessary for you to participate in these tests for they are mainly for internal testing purposes.

Also, please verify your connections to the MDN prior to the Sunday start-up.  If needed, please login prior to that time.

Thank you.
