Shutting down availability zones I could almost see, since it's not that much more difficult or expensive to architect to handle that gracefully. But an entire region? I've never worked anywhere that decided being multi-region was a good tradeoff. At best we've replicated data to another region and had some of our management services there, so in the absolute worst case (which would need to be much worse than yesterday) we could rebuild our product's infrastructure there. Do I agree with this approach? Not in all possible cases of course, but for my employers? Overall, yes. It mitigates the highest impact risks. Going further would have significant complexity and costs. Those companies success or failure haven't been impacted by their multi-region strategy AFAICT.
