When I worked at a grocery store 25+ years ago, having the computer systems go down didn't mean we couldn't check people out. But it was hard enough to deal with that we always waited for them to come back up before checking people out again. Recently, after a hurricane, I heard local supermarkets were checking people out manually. It involved looking up prices of everything (by running to the shelf, I think!) and then writing it down and doing actual math. I was amazed that they even tried it. It's so difficult as to be nearly impossible thanks to the way things are done in normal times. And that's just a grocery store. Medical stuff has to be way, way harder.
