> I also think it's perfectly fine if my site is down for a day or so because I'm away on travel and it's gone offline. 89.9999% has five nines as well. I think this is the key takeaway: host at home unless you want good uptime. I don't host from home when I want the page to be available even if: 1. There's a power outage at my home 2. I need to e.g. change a lightbulb, so I have to turn off the power (and therefore my router and server) 3. Someone accidentally switches off either the router or server

A UPS solves a lot of these problems. You may lose availability during a power outage, but you don't lose uptimes, and those hard shut-offs are nasty for harddrive longevity.

You turn off the power to change a lightbulb? It never occurred to me before that that could be a dangerous activity. You hold it by the glass and unscrew it, then do the reverse for the new one. Your hand should never goes near the socket, right?

> host at home unless you want good uptime. It doesn't even really take much to get 99.999% uptime from a home server. I have my server, cable modem, router, and firewall plugged into a small UPS that can keep everything going for about 30 minutes if the power goes. I've never had downtime due to power interruptions. If I lived in an area where the power was less reliable, I'd use a bigger UPS. In order for someone to accidentally switch off a critical piece of equipment, they'd have to go to my closet and remove all of the boxes and other crap I have stacked in front of it in there. Not likely to happen by accident.

  You realize that 99.999% uptime is 6 minutes of downtime a year? How is your internet even that stable? And do you never restart the machine?
