Consider an e-commerce Web site that normally runs seven days a week, 24 hours a day, generating an average of $10,000 per hour in revenue from customer orders. Experience has shown that:

 - the site becomes unavailable due to operating systems failure five times a week.

 - At each operating system failure, the site is unavailable for 2 hours.

- In addition, the company estimates that upon a failure, it would spend $5,000 on advertising to counteract the negative publicity from such an incident.
