Well, some products/businesses don't need 99.999% uptime and that's fine. Hell, I'm working on a small shop and we had to update some service that is not used constantly by our customers and when I suggested to have a downtime of 5 minutes everybody looked at me as if I were a caveman. The other alternative was to come up with some custom strategy to have two instances of the same service running at the same time and kill one of them when we know the other is healthy. Now, for a service that is constantly used that's a good idea, but for our scenario a 5 min. downtime is fine... we are not Google.
