To be sure - How to avoid AWS US-East 1 downtime

Another AWS EBS outage yesterday evening (UK time), and as before it was flaky old US-East 1. Only Zone C this time, although I experienced a degree of latency whilst helping a client re-launch his webserver in Zone A (praise be once more for AutoSnappy). I'm continaully surprised by the amount of 'cloud aware' businesses who get caught out, however, bad platform design aside, on checking outage history there's an easy option to limit the damage, even if you're running a single instance (and don't use Scalr or haven't designed for for zone redundancy).
