NM spawn timers are not persisted externally, (except for a few that are specially programmed), so they will reset when a world server goes down.
However, just because you can't log in doesn't mean the server is physically down. It could be any number of systems. Servers can be "down" without ever being actually reset. So it's a toss-up.
