We're already using Node.js in production across a variety of high traffic sites. The new My Yahoo, Premier League Fantasy Football, and the recently launched Yahoo Screen, are all running on Node. In the next 12 months we're on track to easily become the largest originator of traffic from Node in the world. We've also built an amazing infrastructure. We run the latest version of Node, host our own NPM registry, and deploy seemlessly from a Github pull request all the way to production. In fact, we deploy more than 400 times, and run more than 360,000 tests everyday.
