Why Is Less Than 99.9% Uptime Acceptable?
Ian Lamont writes "Telcos, ISPs, mobile phone companies and other communication service providers are known for their complex pricing plans and creative attempts to give less for more. But Larry Borsato asks why we as customers are willing to put up with anything less than 99.999% uptime? That's the gold standard, and one that we are used to thanks to regulated telephone service. When it comes to mobile phone service, cable TV, Internet access, service interruptions are the norm — and everyone seems willing to grin and bear it: 'We're so used cable and satellite television reception problems that we don't even notice them anymore. We know that many of our emails never reach their destination. Mobile phone companies compare who has the fewest dropped calls (after decades of mobile phones, why do we even still have dropped calls?) And the ubiquitous BlackBerry, which is a mission-critical device for millions, has experienced mass outages several times this month. All of these services are unregulated, which means there are no demands on reliability, other than what the marketplace demands.' So here's the question for you: Why does the marketplace demand so little when it comes to these services?"
Probably because of the cost. I do network design for a fairly large telco, and let me tell you the cost goes up exponentially with the number of "9"s that the business asks for.
Are these kind of outages really so common? Mobiles phones I absolutely agree with. ON the other hand, I literally cannot remember the last time I lost cable or my internet. I've literally lost power more frequently than either of them (maybe 4 times in the past year) and lost water once. Emails not making it to their destination--again, does this really happen? In the decade plus I've been using internet email, I can't off the top of my head ever think of any "lost" email unless it was sent to a wrong address or something.
I think the term you're looking for is "managing expectations." Here's a little article about it from the IT side. It's something that Microsoft and teleco's have become so good at. If you keep expectations low and give them a little better, they'll be more than happy. If you give the same, but you promised the world, you get a bunch of unsatisfied customers.
As a guy who does communications in the U.S. Navy, I can attest to this. If the United States military can't guarantee 99.999% uptime on communications in all conditions, what makes anyone think it's possible in the private sector?
