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.

Please read the following Zimbra release notes for information about Zimbra 7.1.3: http://files.zimbra.com/website/docs/7.0/Zimbra%20NE%20Release%20Notes%207.1.3.pdf

Details for Patch 1, which will be applied at the same time as the upgrade, are here:

The full backup of Zimbra-mbox3 that runs every weekend failed to complete successfully due to the backup volume going offline.  The volume has been reattached and checked for errors.  A new full backup of Zimbra-mbox3 has been started but this will take some time to complete.  Mailboxes will become locked temporarily as they're backed up.  This should go unnoticed but there's a chance that an access attempt is made at the same time a mailbox is locked.

Unfortunately we're unable to perform any mailbox restores on zimbra-mbox3 until the backup completes.  We're also unable to restore mailboxes on zimbra-mbox3 since the last valid incremental which was on Friday 14th at 1AM.

The other Zimbra mailbox servers are unaffected.

Apologies for the trouble this may cause.
