On September 23, 2008 at 9:00 AM, ERCOT will migrate MOSTML and the listener application to new hardware. This migration is planned so that there will be no need for Market Participant's to change IP addresses. The listener application will have a new URL: https://mostml.ercot.com/ercot-xml/servlet/Listener <https://prlp011n.ercot.com/ercot-xml/servlet/Listener> . During the migration, a brief disruption in TML Market functionality may occur. CONTACT: If you have any questions, please contact your ERCOT Account Manager.
