There have been several incidents in which some root servers have hiccuped, sometimes being down for several days. But since the service they provide has N+12 resiliency, the service itself has never been unavailable. Similarly, the Internet has always had N+1 or better vendor resiliency so IOS can have problems while the non-IOS vendor (or vendors) keep on running. In fact, I would argue that N+1 vendor resiliency is a good thing for you to implement in your network and N+2 vendor resiliency is a good thing for the Internet as a whole. Let's hope that vendor P manages to get some critical mass in the market along with J and C. --Michael Dillon
