Honestly, I pretty much accept that there is a chance of downtime. It is acceptable risk in my situation because the chance of a prolonged outage really is pretty low. I look more at making it easy to restore web apps after a problem occurs. Every hour I take a snapshot of an ebs volume, and retain it for 36 hours. It won't prevent the downtime, but I'm hoping that it will save me future headaches after an outage.
