$250,000 an hour? They are losing that much?!? Are they a rich company? Oh my!...
The answer to your question is a complex one. Have you ever seen Orange County Choppers? That huge Machine that they use to drill out custom rims are sold by Sandvik. We sell them no only to motorcycle shops, but airlines, hospitals, ect. Those machines are $600,000.00 and run about $2000.00 a month to maintain with tools, maintenance, spare parts. ect.
If my server is down and the sales guy cannot sell one of them? What if Orange County Choppers wanted a new part? If they cannot order it, they will go down the street right? We are a Global Company, but personally (thru my servers here), I have all of Barzil, Chile, Argentina, Mexico, Canada, and all of the USA has to come thru here to conduct their business.
That number is a caculated guess on "How much business we COULD have done in 1 hour if that server was available?
We sell other stuff, but this is just an example.
And I just checked, we actually have 12500 employees that technically work thru here in one way or another. Not all of them use computers, but if you have 12500 people making $30.00 p/hour. Standing around for an hour is $375,000.00 for doing nothing!
