Incident Update: Brief Interruption on B Feed Power Supply
Scheduled on 28/01/2026 14:35:00 Status In-Progress Estimated finish 30/01/2026 23:59:00Incident Summary
Yesterday, we experienced a brief interruption affecting the B Feed power supply within the data hall.
Initial Assessment
Initial inspection suggested a potential failure of a Power Distribution Unit (PDU) within the data hall, which was believed to have caused an overload on part of the B Feed circuit.
Further Investigation
Following a more detailed review of electrical and UPS logs, we have confirmed that the root cause was a brief interruption in the incoming electricity supply to the data centre, commonly referred to as a brownout.
A brownout is a very short-duration voltage drop and is often only noticeable as a brief flicker of lighting, after which normal voltage levels return.
UPS Behaviour
During this event:
- The A Feed UPS operated as expected and successfully carried the data centre load.
- The B Feed UPS, however, did not fully sustain the load during the brownout, resulting in a brief interruption to the B Feed supply affecting sections of the data hall.
Current Status & Actions
- A UPS service engineer has been engaged and will attend site to inspect the B Feed UPS.
- The purpose of this visit is to establish why the UPS did not maintain load during the brief supply disturbance and to carry out any required remedial work.
- Until this investigation and any necessary repairs are completed, the B Feed power supply is being treated as “at risk.”
Customer Impact & Guidance
- Customers with single-powered equipment connected only to the B Feed should consider this equipment at risk.
- If you would like your equipments power feed to be migrated from B Feed to A Feed in a controlled manner, please contact us and we will arrange an agreed change window.
Apology & Monitoring
We apologise for any inconvenience caused. Our engineering team continues to monitor all systems closely to ensure any further impact is kept to an absolute minimum.
If you have any questions or would like to discuss mitigation options, please do not hesitate to get in touch.
Kind regards,

Informational Notice: A-Feed PLC Power Supply Issue (No Service Impact)
Scheduled on 03/01/2026 18:28:00 Status In-Progress Estimated finish 08/01/2026 13:00:00Dear Customer,
This notice is to inform you of an at-risk condition identified today, 3 January 2026, relating to one of the PLC controllers associated with our A-feed switchgear.
18:28 – An issue was detected affecting the electronic power supply device serving the A-feed PLC controller.
18:35 – Engineers were on site and investigating.
18:55 – The root cause was identified as a failed electronic power supply device.
The B-feed remains stable and fully operational. As a precautionary measure, signalling from the B-feed generator has been configured to operate the A-feed, and both generators are capable of supplying the A-feed if required. The affected PLC controller also powers up correctly once generator power is present.
A replacement component has been ordered, and an engineer is scheduled to attend on Monday to install the part and return the system to normal configuration.
There is no significant risk to customer services, and this notification is issued for information purposes only.
Further confirmation will be provided once the replacement has been installed.
Kind regards,
Operations Team
