Saying 'everything has outages' is kind of disingenuous. There are many computer systems in the world today that can be considered to have practically perfect up-time. Mainframes have uptime measured in decades. I realize the concept of 1 gigantic iron box in a heavily-fortified installation with 2N+1 redundancies throughout is still not enough to ensure 100% uptime. But, when is the last time you swiped your credit card and had a failure to process the transaction?
