Tonight at 9PM GMT we will be restarting the Zimbra service.  The restart should take no longer than 15 minutes.  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.

The restart is required to reinstate valid server certificates on our Zimbra platform that were reset during the recent upgrade.

I'm pleased to let you know that we finished our platform upgrade to Zimbra 6.0.5 at 18:00, one hour ahead of schedule. Our post upgrade testing and system monitoring shows that everything appears to be running smoothly. Thanks to the Zimbra team for producing such a great installer :-)

Just a quick update on the upgrade - so far all is going well:

 - Proxy, LDAP and Mbox servers are all upgraded and access is enabled.

 - MTA servers are being upgraded now and should be finished shortly after which queued mail will be delivered to the mailboxes.

We will post an all clear note when we have finished the MTA servers.
