Due to a memory error, we have lost access to the management unit in our main cisco switch stack in Telehouse and therefore need to reboot one of the switch nodes.

Although the switches contain redundant controllers, we cannot be sure that the backup will take over, and there may be a short outage to our core network whilst it reboots.

As a precaution, we plan to shutdown most of our virtual servers to a bare minimum, and specifically we will switch off those providing the email system (as their hard disks are accessed via network based storage), and therefore no email collection or delivery will be available during this maintenance window.

We do expect our voip platform to continue working, although some calls may be dropped.

We expect this work to take under 15 minutes to complete, but please accept our apologies for this interuption to service.

Update - 03:15

The switch was successfully rebooted at 01:30 and nearly all services were fully functional by 02:00.  At the time of writing (03:15) we believe all services are back to normal.

Thank you for your patience during this maintenance and we apologize for any inconvenience caused.
