Summary

Make it possible for publishers to self-host the AMP runtime, without breaking AMP validity.

Motivation

The benefits are:

• Independence: AMP runtime and components no longer needs to be loaded from Google servers for AMP First sites.
• Control: AMP First sites can align the roll-out of a new AMP version with their own QA (this won’t help them if pages are served in SERPs). They can also rollback a broken runtime version themselves.
• Performance: faster page load and TTI by avoiding an additional HTTPs connection.
