as regulation from government in the tech space can be
interesting as they are not always up to date with stuff. <br>

<div>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>

There is a risk no matter what when switching
from power supplies taking extra load they would
not usually take as well as swing load issues
with PDU's.<br>
