Power is critical for any servers or network equipment. As with any mission critical system, redundancy is a must and we aim to keep all systems online 100% of the time. To achieve this, we use dual-PSU in every server and then connect these to an A+B power feed to further duplicate the redundancy.

In the case of failure of a PSU unit, we simply unplug it, replace it with a new PSU and plug it back in - everything is fully running and operational throughout the maintenance process.

The datacentre also has large-scale Uninteruptable Power Supplies (UPS) in a modular configuration which gives itself N+1 status too.
