Re: Power problems
That entirely depends what the problem is. Sometimes the issue is getting the current from the generator to the racks. An outage of this length almost guarantees that it's not just a case of a blocked fuel filter or stuck changeover relays.
Most buildings of this type have existing external connections for a mobile generator and a reserved parking space all ready to go.
It's not something you can bodge because once the power's back on no-one will let you turn it off again for a long time so a long outage indicates to me that something significant has broken and is taking time to repair properly. That could be a distribution board or a busbar or something of that order.
If you bodged temporary power with extension leads it would be a) quite dangerous but also b) a permanent solution until you can agree a changeover back to normal power with every single customer affected. I'd trust a generator for a week or so, I wouldn't like to be relying on it six months later.
