On Sunday 13th November 2011 starting at 4pm GMT we will be performing an upgrade of our Zimbra platform from 7.1.0 to 7.1.3 P1. We expect the Zimbra upgrade to take approximately 3 hours, although the window is scheduled for 4 hours.

Maintenance Start: 16:00 (GMT) 13th November 2011

Maintenance End: 20:00 (GMT) 13th November 2011

Once we commence the Zimbra upgrade all incoming email will be queued, access to the Zimbra servers will be restricted and Zimbra customers will not be able to access their mailboxes.
