in other words: if google goes down, you can do other work meanwhile or go to lunch, if your system goes down, you have to spend your time/money to fix it.
If Google got things fixed over a lunch I would entirely agree with you. The problem is they take days to get started, don't give you much feedback about what the problem is, and I've never actually had a bug ticket fixed. So, yes you can keep on doing work, but you also will keep on not getting emails/business.
