The departmental authenticating outgoing smtp server gateway.eecs will be down for a needed reboot to activate changes delivered by some RHEL patches.
Though the scheduled downtime is 7:15am to 7:45am, we expect actual downtime to be less.
UPDATE
[2020-05-20| kraitch ]
gateway.eecs is back up. Maintenance has been completed.
