I worked for a company that had acquired a B-list, top 20 mmorpg - its database was mssql and had been running 24/7 for 5 years, with no way to back it up, no safety net, and an increasingly pissed off player community suffering degrading service. Everyone was terrified to reboot. They started bouncing paychecks before I got to see the drama come to a head, but I'm obsessive about proper levels of redundancy anymore. Don't build fragility into a system, and at least leave yourself a means to fail gracefully.
