Many commenters seem to think the author is saying that we should stop caring about uptime, when what he's really saying is that we should be reporting time (i.e. number of hours down in the last month) rather than just reporting an opaque percentage that hides the problem.

I want a good chart not a percentage, because one service being down at 2 am for 3 hours is not the same as another service being down for 45 minutes during my peak hours of productivity.
