Interesting that they still host the cloudron.io site on Amazon platform

ping cloudron.io -> 54.192.7.94 -> server-54-192-7-94.dfw3.r.cloudfront.net (Amazon Technologies) [1]

Correct me if I am wrong but you are pointing out that their website is on a CDN. Are you saying they need to host their website on Wordpress/Ghost? AFAIK, Ghost & Wordpress do not easily scale compared to a CDN if your site has heavy traffic (which landing pages must be engineered for as opposed to small blogs).
