I think there is something to be said for having redundant domains for backend apis for an app, with redundant dns. If one was to go down have the app fall back to the other. Not much help for a web app of e-commerce business though, domains are are one single point of failure that you can’t easily fix.

But it’s one of those things that isn’t mission critical while building a business and so can easily be overlooked. I see redundancy in the backend, or at least a disaster recovery plan that covers single points of failure, the same as normal backup procedures that most of us already do.
