Here’s an idea they might want to think about. They raked in what, $100 million in exam fees for the June exams?
Their issue is about the easiest one to deal with. They have the luxury of knowing the exact day and time that their servers will be strained. They can simply rent some extra space for that day, and it won’t cost very much at all. In fact, I think Amazon Web Services will automatically adjust for them to meet demand if they were to use that service.
The issue is either one of incompetence or extreme penny-pinching.
