Just before 5:00am this morning we suffered a power failure in our Maidenhead datacentre affecting all equipment. The outage lasted approximately 30 minutes. Apologies to all customers with services provided from Maidenhead. London and Amsterdam were unaffected.
The datacentre have issued the following statement:-
Following on from the issues this morning, we are continuing to work with suppliers to find the cause of the outage.
Current investigations appear to have identified a phase detection relay which may have failed in the generator auto-changeover panel. This could have caused the panel to think there was a mains power failure when in fact there had not been.
The UPS systems worked as expected without fault, however due to the mains being forced off by the potentially failed relay, and power from the generators also locked out, the UPS batteries fully discharged after 10 minutes resulting in a critical power failure.
We have engineers collecting a new relay, along with other spares that maybe needed from the manufactures in North Yorkshire. We expect these to arrive in the early hours of tomorrow morning.
During this time we have manually disabled the mains auto changeover system in order to aviod any potential further mains cuts. In the event of a real power outage on site we will have staff perminatly onsite to operate the generator changeover procedure manually.
This should be treated as an ‘at risk’ period for customers in BlueSquare 2 & 3 until further notice.
Once we have further information we will update this ticket.
We apologise for any inconvenience caused.
