Mandrill Planned Downtime and FAQ | Mailchimp

Hi all - wondering if anyone else using mandrill is having any concerns about this outage planned from 1-5am New York time on 11 January, 2020. I use the SMTP method to send mail from our discourse, and am suspecting that messages will be deferred and sent later by discourse so all will be well. Or should I assume discourse will not know what to do with the down server and instead just take my site down for the duration of the planned outage? Or is there a way to pause outbound mail so all messages get sent after it’s over?
