On Sunday 21st February 2010 starting at 4pm GMT we will be transferring some of our Zimbra services to faster hosts.  This transfer requires that we shutdown the Zimbra service for a short time.

17:06 - UPDATE: Connectivity is restored. At this stage it looks like a port issue on one of our firewalls - we have forced a failover which has restored the connectivity and we are investigating further as to the cause. Please accept our apologies for the short delay in service.
