There are a good few ways of saying it.  ”Too err is human.”, Murphey’s law.. In Finland we can might also hear, ”Elämä on..” (life is), or “Ei mennyt niin kuin Strömsössä” (It didn’t go as in Strömsö (village)).  The point is, that despite all our best planning, for one reason or another things just don’t work out as we hoped.  Having a disaster recovery plan is paramount.

Even if you not are actually desiring failure, you are prepared for it?  Your data is backed up and easily accessible.  Depending on your budget, you have spare parts on the shelf.  You maybe even have an automated system in place which keeps key systems running seamlessly whilst repairs are taking place?
