This technology problem is a good metaphor for Facebook overall as a company. There is nothing fundamentally wrong with having your app regularly polling for DNS records when it can't find them, but that can be an actively harmful approach when you are the size of Facebook. Being that size comes with a whole swath of extra responsibilities to ensure that your behavior doesn't end up harming society as a whole.
