It didn't just crash, it crashed 100% of computers running it at that time and in a way that required physical intervention to fix. So I think you can considers this quite different from regular crashes because recovery is much more difficult and because it affected a lot of computers simultaneously.
On top of that there are companies that had failures of their own in their recovery procedures. But even with good procedures this can be a significant outage because it is not trivially reverted and would typically affect many configurations that are redundant for many other failures.
