From: Joe Pluta <joepluta@plutabrothers.com> > Has anybody thought to do the math? 99.9999% uptime means a total of THIRTY SECONDS of unscheduled downtime per year (actually, 31 and change). The 99.9999% has a special marketing significance. It is a failure rate of 1 in 1,000,000, which is better than 3.4 in 1,000,000. what is this mysterious 3.4? It is the six sigma level. Search on Google for "six sigma".So if you are at the 99.9999% level you are better than six sigma (the ultimate mark of quality). So there is great incentive to claim to be better than six sigma, whether you are or not. +--- | This is the Midrange System Mailing List! | To submit a new message, send your mail to MIDRANGE-L@midrange.com. | To subscribe to this list send email to MIDRANGE-L-SUB@midrange.com. | To unsubscribe from this list send email to MIDRANGE-L-UNSUB@midrange.com. | Questions should be directed to the list owner/operator: david@midrange.com +---
