Yup. The whole thing should be treated as an extremely close near miss. They got it back up and running in a day, otherwise things could have gotten REALLY ugly.
(Though even in that hypothetical case - this wasn't a zombie apocalypse. The rest of Europe was still operating normally, so even in the worst case, there would have been ways to supply the population and restore order. But it would have been like an international response to a major natural disaster instead of only stressing out a few technicians.)
