You might be amazed at the type of uptime some companies have. My former
employer had a datacenter capable of running somewhere around a week without
any external utilities (they were hardwired to three independent power
utility companies) -- Enough power, food, water, and air in-building to run
a week without restocking supplies.
This isn't uncommon when you're talking backbone infrastructure.
Honestly, a power failure is one of my least worries when it comes to full
scale data centers. I'm only about $500 away from a generator at my house
that would kick in and keep my servers up in the event of a power failure,
but at this point none of my clients are interested in paying extra for that
feature. Even doing it on a very small scale, 4-6 servers, isn't really
that hard to afford.
(I'm talking 10% more then their usual monthly fees for a year or two, not a
lifetime commitment or a huge upfront cash outlay)
