We've made some special wording updates to Fastly services guides we want you to be aware of. Because Fastly uses the TLS (Transport Layer Security) protocol for secure HTTP connections, we've updated the references in all of our documentation to use the term TLS unless explicitly describing the now deprecated SSL (Secure Socket Layer) protocol or when mentioning settings that display SSL in the Fastly application.
