As always I recommend people practice Chaos Engineering [0] to minimize the impact of such events. Even if the complexity of cross-region failover is to expensive, having some sort of graceful failure is preferable to simply dying. Netflix's Simian Army [1] toolset is particularly useful here, though I don't see an OSS version of Chaos Kong (which simulates the failure of an entire region) sadly.
