>>that's not the point. If YOUR servers go down, then it's in your power to get things fixed. You can apply what resources (or not) you see fit.
In a medium-large business with dedicated sysadmins working 24/7, sure. For a small business where people go home at night, not so much.
Let's face it, the longest outage we've seen has been something like a day, to fix a total global screw up. That's pretty impressive... I'm pretty sure Google's thousands of people working 24/7/265 are going to fix things faster than a developer who got lumbered with the sysadmin work because he knows how to build a home network :)
I want to focus on developing stuff, not managing my network.
