Exchange Issue

Wed, 09/05/2012 - 19:43

We are currently investigating an issue with our hosted Exchange email environment that may prevent sending or receiving email (inbound email will be queued on our anti-spam gateway). We will update this status shortly with further information. We apologise for any inconvenience caused.

Update 21:07: All Exchange services re now back online and we are currently compiling information on the cause of this issue.

Update 14/05/2012: This issue was caused by a failure of the firewalls that sit in front of the Exchange environment to manage a large increase in connections generated by a denial of service attack. The attack was brought under control and work is ongoing to understand similar attacks could be better mitigated in the future. We apologise again for any inconvenience caused.
