I'm not sure about that either. If it was my product I think I'd want a polite on-brand 500 page saying my hamsters are working on it. Seeing something that suggests hosting is down doesn't frankly matter to me, even as a technical user... and to someone in between myself and my mom, with enough knowledge to understand what a "hosting company" is... I wonder if they might feel ripped off as well: "Oh great. I gave this company my money and they don't even have their own servers!"
