Live timing is a completely different animal. If it shut down during the Noble race, it was likely related to the set-up or remote connection at the track.
This is nothing like All Access ... Not a system run directly from HQ. Simply a laptop connected directly to the timing system using a local internet connection. Every division has a set-up and hooks it up themselves at the facility. Quite low tech. Not all tracks are set-up with National Event like connectivity and compatibility. Therefore, if the track is more remote and the local internet sucks ... system works poorly or not at all.
I would guess 1 of these happened at Noble ...
1) Internet was lousy and just stopped working, or
2) Someone forgot to check on it and re-start it if there was an interruption in service
