As a reminder......the deadline for migration from the Market Data Network (MDN) to the Market Data Platform (MDP) is January 31, 2006.   Due to a high increase in market data message traffic on the existing MDN, and the associated potential risk, please be aware that this new deadline cannot be extended again. Be assured that the increased message traffic has been accommodated within the MDP infrastructure.

All Market Data Distributors are expected to use the MDP network in production by mid-January or a specific January date on which MDN logins can be disabled must be provided to Market Data Operations. All remaining MDN logins will be disabled on January 31^st.

Please email one of the individuals below with your target date for completion of the MDP migration.   We are rigorously tracking these dates to help ensure that everyone is able to meet this critical deadline.
