"Goes up" could indeed be what it does. The billions spent on it have already "gone up" with each delay. "Monitoring intermittent LH2 Leak, Core Stage Replenish Valve".
I don’t envy this service crew, out there torqueing some bolts, while the safety crew stands off some distance, on the ground, for a really good view of the service crew if they happen to set off a fire or explosion.
There, they said it, could push out the launch window.
Hope it’s successful, I love night launches. For that matter, a night explosion wouldn’t be bad, either. Either way, watch for flying dollar signs!
