Our Zimbra cluster is currently experiencing difficulties due to a DDoS attack.
Engineers are actively working to mitigate the problem and to add defences to reduce any further risks.
As a result the Zimbra Cluster will be reduced and possibly unavailable briefly as we work to address the issue.
Apologies for any inconvenience this may cause.
UPDATE
The maintenance and upgrades / reboots have been completed
Apologies for any inconvenience
