            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>

            equipment in a DC environment now a days when you can buy
            refurbished servers that come with two PSU as standard even
            when you buy them without raid.<br>
            > Also for anything that is really really mission
            critical you should have it hosted in multiple datacentres
            anyway so if something stupid does happen that you can't
