At 14:50 a PDU in HY DC failed.
This caused some equipment to lose grid redundancy.
At 20:30 , all equipment was moved to temporary failover grid redundancy until DC operator can remedy failed PDU.
The root cause was a short circuit in a server power supply causing fuse to trip.
On Tuesday during office hours, DC operator will attempt to remedy the tripped fuse and move equipment back to original PDU.
Impact: No service disruption of network connectivity (redundant power). Reduced Grid redundancy between 14:50 – 20:30.
