We put some efforts into our default origination service a few years back to prevent default from being announced if the pop became isolated for some catastrophic reason. I recall once when someone upgraded the route processor of two different routers in a pop at the same time resulting in isolation until the configs were placed on the new RE for other devices in the site. Things happen and preparing for them is the first step to survive. - Jared
