On June 19, 2020, U.S. EPA’s Central Data Exchange (CDX) will be decommissioning one of its Exchange Network Node endpoints in order to increase operational efficiency and reduce maintenance costs. The retiring endpoint is associated with a seldom used service called the Node Relay located at https://noderelay.epa.gov/
Most partner agencies will not be impacted by this change. If you are still pointing your data flows to submit to the Node Relay endpoint, please update your settings to use https://node2.epa.gov/
If you have any questions or need support, please contact the Exchange Network Node Help Desk at firstname.lastname@example.org.
