What is notable to me is the surprise received by those who purchased hosting in multiple geographies to survive a datacenter-wide issue. I hadn't thought much before about the effect of centralized IT management decisions on availability. Perhaps those who really need uptime will now consider using another hosting provider as fail-over. Not sure how the DNS issues would play out as network-level load balancing isn't something I know much about.
