The conversation surrounding the development of a custom CDN for Auro versus utilizing a third-party service has been recurrent.

Recommended solution

The work needed to address this policy announcement should include the following;

1. Add a page to the Auro doc site that clearly states Auro's position on CDN support. Clearly state that Auro is NOT providing a CDN solution and the solutions described in each repo are demonstrative and instructional and clearly come with some risks.
2. Update every repo README to support this statement and link back to the policy document.
