It comes under the Victorian Occupational Health and safety Act 2004
from the bit of reading I did yesterday.

As someone who has run colo facilities before:
It should be made completely clear during customer onboarding that the
facility operator can temporarily shut down a power feed at any time.
Advance warning should be desirable but optional.
If there is risk involved in doing that, it’s your job to mitigate it.
The facility operator doesn’t know which bits of equipment in your
tenancy are critical, and they’ve already told you to dual-feed where
possible and use a rack-mount ATS for single-corded equipment.
Power work should be done during business hours, because it’s almost
impossible to get emergency support or source replacement equipment
out of hours.
If it isn’t safe to take a power feed offline during business hours,
then you (the customer) have a design problem to solve.

both feeds at once because that would be stupid and if the entire DC
was offline for too much time then that would put the owners in a
rather awkward situation legally, as after say 8 or 10 hours of
downtime it wouldn't be good for the owners lets put it that way.

come with two PSU as standard even when you buy them without raid.

have it hosted in multiple datacentres anyway so if something stupid
does happen that you can't control you at least still have services
online as the load balanced services would just switch.
