<div class="PlainText">As someone who has run colo facilities
before:<br>
<br>
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.<br>
<br>
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.<br>
<br>
Power work should be done during business hours, because
it’s almost impossible to get emergency support or source
replacement equipment out of hours.<br>
<br>
If it isn’t safe to take a power feed offline during
business hours, then you (the customer) have a design
problem to solve.<br>

that would be stupid and if the entire DC was offline for
too much time then that would put the owners in a rather

downtime it wouldn't be good for the owners lets put it that
