while all of the above engineering solutions work, I wish they adopt a human centric solution. When there is too much demand and too little inventory, they could introduce some kind of lottery system where they accept partial payments through out the day and then randomly pick tickets in a lottery (individuals and group bookings as well). In this way, fans can avoid the mad rush, ticketing systems don't have to handle the peak mad rush for 10 minutes.
