DETAIL: We are currently experiencing some unexpected problems with our service delivery.

RESPONSE: We are investigating this and expect to have this resolved promptly.

UPDATED 16:20: We were performing a routine maintenance operation to expand disk space. This normally requires no downtime, however the operation hung causing a cascading problem which required us to restart the entire service. Because the restart was unscheduled we took great care to minimise any associated risks. We apologise for any inconvenience caused.
