Chromium HSTS preload

Strict-Transport-Security is an HTTP response header that signals that browsers should only access the site using HTTPS.

For a higher level of security, it's possible for a domain owner to preload this behavior into participating web browsers. Chromium maintains the HSTS preload list, which is the de facto standard that has been adopted by several browsers. This service checks a domain's status in that list.
