[Resolved] Intermittent Access

9:45am: We've just lost one of the perimeter servers responsible for balancing the website, client and webmail traffic. The remaining perimeter servers and the entire mail cluster itself are all online and operational, no email will be affected. We'll keep you informed here when any updates are available.

10:10am: All back online, a single drive failure in the perimeter server caused it to fail completely. We naturally use RAID (basically the use of multiple disks to act as one) to prevent such failures knocking out individual servers but for an as yet unknown reason the RAID array failed with the drive. We are now trying to determine why this occurred.
