The current wording suggests that a target is not reachable at all, although it might also get set when the target was reachable, but there was some other error during the scrape (invalid headers or invalid scrape content). UNHEALTHY is a more general wording that includes all these cases. For consistency, ALIVE is also renamed to HEALTHY.
