How do you measure downtime? The datacenter isn't able to offer power, internet, and cooling to the machines within it? If your data center goes down less than once a year then I'd suspect you are delaying critical maintenance procedures. A 99.999 uptime datacenter is still down a little bit each year. If you've designed your service with the assumption that the data center will be up 100% of the time, I'd be worried that you've also assumed that there may be design assumptions that your hardware never requires BIOS upgrades, or that none of your co-workers are capable of accidentally kicking a power cord.
