LONG DESCRIPTION: ERCOT is implementing changes to the Domain Name System (DNS) resource name indicated below. As a result, IP addresses are subject to change without notice.

Market Participants (MPs) are encouraged to ensure their whitelists include the FQDN to avoid any interruption of service.
The changes will be implemented between the hours of 17:30 and 20:30 on June 22, 2017.
Based on MP configurations users may experience an outage of up to 30 minutes if attempting to access this site during the change window.
