It was my understanding based on the website's copy that this was also a DNS GLB: Expanding on Cloudflare’s highly available DNS infrastructure and global Anycast network, the Cloudflare Traffic Manager is a cloud-based load-balancing solution that enhances the performance and availability of your Internet facing infrastructure. Designed for scale, flexibility and robustness, CTM enables your applications to deliver the ultimate end user experience through the highest level of performance and reliability. It has since been clarified that this product has the ability to re-route traffic based on availability and it does not base its balancing in returning different results for the same DNS query. P.S.: I'm not saying that the copy "says" this is DNS GLB, I'm just saying it was vague enough for me to assume it was a DNS GLB.
