At approximately 7:40 AM PT/10:40 AM ET, our mail server experienced an unexpected restart. Upon coming back online, the server applied some automatic updates.
Despite the server coming back online on its own, the mail server was refusing connections from our application servers. This led to some emails not being sent to our users.
The issue was resolved at 10:35 AM PT/1:35 PM ET.
This partial outage was restricted to our email systems, and no data was lost during the time of the partial outage.
