First if this has never happened to You, you are one of the lucky ones. Here is my experience while working from London (2012-AUG-18 07:41).

The key questions:

  1. How often will this Cloud application be unusable ?
  2. How frequently this might happen ?
  3. What part of the global infrastructure was at fault?
