> What would a small business do as a contingency plan?
Depends on your definition of small. If it's small enough not to have a dedicated infrastructure team designing multicloud solution, then the contingency plan may be: switch DNS to a static site saying "we're down until AWS fixes the issue, check back later".
Otherwise it depends on your specific scenario, your support contracts, and lots of other things. You need to decide what matters, how much the mitigation costs vs downtime, and go from there.
