We are writing to inform you of upcoming routine maintenance at the cluster's data centre. Over the next three weeks, the facility will be conducting "Black Building Tests" to verify the resilience of our backup power systems.
Overview & Schedule:
These tests are performed annually to ensure that onsite generators and backup systems activate seamlessly in the event of a grid failure. This year’s testing is scheduled ahead of essential grid maintenance by the local network provider.

POSTPONED - Window 2: 26 January 2026 | 08:00 – 17:30 GMT
Service Impact:
We do not expect any downtime or impact on your services. While all power maintenance carries a nominal risk, please note:
- Proven History: These tests are performed every year, and to date, they have never resulted in a service interruption or outage.
- Precautionary Measure: This notice is provided for full transparency so that you are aware of the testing windows.
- On-site Monitoring: Specialist engineers will be on-site to monitor the infrastructure throughout the entire process.
We will continue to monitor our systems closely during these periods. If you have any questions, please reach out to your Account Manager.
