What you're suggesting is something for large companies. Most of these companies affected probably don't have time and resources to develop and pay for alternatives to every single third party service they require. And why would they? They have contracts you'd expect to be honored. Seems unrealistic especially since the majority of times when these services go down it's likely just a short time so they probably have abstracted around them to avoid unexpected failure and just have routine, down time failures.
