The cost and impact of downtime needs to be accurately and realistically measured. For some businesses, minutes down cost thousands. For many business, the impact is about irritated employees, not significant lost revenue. We all tend to think we need bulletproof systems that have Six Sigma uptimes, but that really isn't always the case. I'm not in national security or healthcare. If we have systems down for a reasonable time, no one is going to suffer permanently. It will be a major inconvenience, but our business will survive. That kind of realistic view of our true business needs has helped us make appropriate and responsible business continuity investments.
