I really liked your write-up. As natch mentioned, it will be great to include more details in the article. I like the detail level of Digital Ocean articles.

It seems based on my recent trial experience with CloudFlare that both CDN startups might have this issue of incomplete/insufficient instructions and information for their users/customers to properly implement the solution and lot of assumptions about the skill level of users implementing the solution.

Actually, I landed up providing detailed instructions to CloudFlare on configuration and testing of their service. And a list of questions, answers to which should be readily available if CF is targeting enterprise customers.
