IT is not what it was many years ago, I am talking before the evolution of the Internet as we know it today! Back in the days, when you were bumping into a "serious" problem, well hope you had good contacts and/or friends with excellent knowledge or a good library! Last resort there was always the company that made the appliance / software that could help but good luck it they were not 24/7! Not all the problems happened on a Monday to Friday basis between 8pm to 4pm and that's if you were in the same time zone than your service provider!
