what does "demand outstripped facility"mean?
The atmosphere of tension was heightened by what appeared to be a communications crisis. Parkland's switchboard operators saw their lines pre-empted—apparently by people dialing 9 on hospital extensions—until all twelve switchboard alarm lights were ablaze, indicating an absolute overload. The implication was that demand had completely outstripped facilities, cutting off the emergency area from the outside world.
