NWS will be transitioning NWWS-OI services from primary to backup on September 9, 2019. Based on corrections to NWS systems during the last transition, no action should be required; i.e., all accounts should automatically transition over with only a slight delay. If your system should fail, the backup IP address is 140.90.113.240. Check the NWWS webpage for additional information.
A return transition from backup to primary is planned for September 11, 2019.
