[Mailman-owners] Mailman Software/Server Upgrade - Nov 19

The Mailman server will be upgraded on November 19th, starting from 10:00 AM MST. If all goes well, it will be down for an hour, but expect at least a three hour window. The upgrade has been tested without taking the original offline, and looks good. The original needs to be taken offline in order to make sure the databases and stored data syncs properly without emails coming in during the transition period. Any inbound emails will be held until the mailman server comes back online. If the upgrade fails, the old server will resume service until the problem can be isolate and resolved. If the old server has to be put back into service, we will schedule a future upgrade date to attempt again.
