Further update on the outage today. The incident is a joke to me, four layers of redundancy on power supply, resulted in hours long outage on standard trigger?

-------
Source of incident identified Following preliminary investigations and analysis, the outage has been traced to a malfunction in the uninterruptible power supply (UPS) systems deployed at the SGX data centre. Power is supplied to the data centre from two separate substations. These sources are in turn connected to
individual UPS systems providing four layers of redundancy. Resulting from a momentary fluctuation in power supply from the substations, the UPS systems
switched to its internal power source. However, the internal power source in both UPS systems malfunctioned.

Can they unveil the brand of the UPS used?
Bought from AliExpress and selected the one with the lowest price?
