This website is currently returning 500, so I'm unable to read the article. This is because it is configured as a server-side rendered website, as opposed to a static website which can be delivered by a CDN. I wish people would stop doing this. The core functionality of a web page (including "blog post" type content) should be entirely static assets delivered by a CDN. Auxiliary functionality can be delivered by a server, an the webpage should gracefully degrade when the server breaks down.
