Re: [downtime] CS Email Downtime, Thursday, November 5, 2015,

As you may have noticed, this upgrade was not completed this morning due to issues with the upgrade process. Some critical parts of the system were successfully upgraded, which should allow us to upgrade more components in a less-disruptive way, but the process is not completed at this time.

More updates will follow at a future date. Thanks for your patience.
