From a technical stand point, how difficult would it be for a ticket vending machine that is out of service to check if others at the station are in service and tell people this?
I was at Dorking Deepdene and the ticket machine was out of service with a message to say use the ticket office.

The station has no ticket office but the nearby Dorking Main does if you know where you are going and have time.
However the other side on the bridge was another ticket vending machine and that was working.

I told someone the ticket machine was out of service and they went up to platform 1. Little did I know the other one before the stairs to platform 2 was working.
There is a slightly caviate that maybe both were out of service and suddenly sprung into life as I walked between them but I doubt it.
