On Saturday the 28th of March at 9PM (GMT) we will be installing a new SSL certificate on our Zimbra platform.  This certificate will replace the current one which is due to expire in early April.  Zimbra will be unavailable for a short period of time during the installation.

Maintenance Start: 21:00 (GMT) 28th March 2009

Maintenance End: 21:30 (GMT) 28th March 2009

Although 30 minutes has been set aside, installation should take no more than a few minutes.

During the maintenance window 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.
