3:45 PM Pacific — The control panel for MAX Mail is back online.  The issue was due to a hardware problem with the front-end cluster.

The good news is that in resolving the issue, our engineering team was able to do some of the work that was planned for the maintenance window this evening.  As a result, we expect that the maintenance window for later this evening will be shortened significantly.

We apologize for any inconvenience.  Mail flow was not impacted by the issue.
