From https://hstspreload.org/ (Google’s submission form to be included in its HSTS preload list, from which Mozilla and Microsoft get hostnames for their own preload lists) -
Strict-Transport-Security: max-age=63072000; includeSubDomains; preload
The formal limit has been raised by Google and is being recognized as valid by the above listed browser vendors. I’d like to see Cloudflare implement the option of raising the limit within its dash to two years from one, giving users more flexibility & allowing for the implementation of the latest HSTS guidelines. Thank-you.
