Identified
We have been informed by our data centre partners that HV-B power feeds are running on generators
"The site has reacted as by design with the UPS and generators taking load. Initial inspections show that no services have been lost, all cooling, power and IT services have not been impacted. Fuel levels have been checked and we have enough fuel to support the load with generators for 50 hours. Specialist engineers have been called to attend the generators and ensure we have the necessary support while on load."
