Blog status and where to go
We have a few issues with our blog.
Our template is broken. Comments are displayed out of the intended layout.
Our blog is generating a lot of page views and has become quite expensive (more below).
Our blog has become quite popular and has received around 300k monthly "visitors" and above 1.5M "page loads". This is bumping our expenses significantly and we are evaluating various options regarding caching.
Using a CDN like Fastly, Netlify, or Cloudflare
Caching via Varnish could create a bottleneck for our blog and a single point of failure.
In the medium term we could also evaluate what we want to do with our current blog.
There is a Drupal static caching project called Tome that we could use together with drupal comments from pantheon.
We could migrate the blog to a static content generator and use a separate system for comments.
