They did have more people. The problem is not everyone in the group knows the code to the same degree. Even when you have someone on station who's supposed to take care of problems, if it takes him more than about twenty minutes to find the problem they're going to start calling the rest of the team. If you're good and you have a reputation for being good they're going to call you. I got 3:00 AM calls because I'd written a particular piece of code even though a half dozen of my colleagues were already on site and awake. Put yourself in the manager's shoes. You can not tell the customer he's needs to wait two hours for the people on site to come up to speed on the shipping module (or whatever) because the guy who wrote it needs his beauty sleep. There's too much money involved.
