Earlier this week, about a million Swedish Internet sites went down for an hour when routine maintenance caused disruption to every single .se address (the country's domain). The problem was caused by an "incorrectly configured script" in an update of the .se domain. Imagine if this would have happened to the .com domain, taking down tens of millions of websites around the planet. It probably wouldn't have stopped the world from turning on its axis, but it may have come pretty close.
