Cloudflare Leak: Which sites has Cloudbleed affected?

It hasn't been a very good week for Cloudflare's security team. Late last week, Travis Ormandy from Google's Project Zero discovered a rather large memory issue that was potentially leaking sensitive information from websites that use Cloudflare. That isn't the best news to hear when you consider that Cloudflare works with over two million different websites, including some heavy hitters like Fitbit, OkCupid, and Uber.
