Subject Re: 99.999% uptime - Operations Best Practices?
Date Wed, 22 Jun 2011 23:17:43 GMT
In my opinion 5 9s don't matter. It's the number of impacted customers. You
might be down during peak for 5 mts causing 1000s of customer turn aways
while you might be down during night causing only few customer turn aways.

There is no magic bullet. It's all about learning and improving. You will
not get HA right away, but over period of time as you learn and improve you
will do better.
