Ask HN: Is this a fast page for mobiles?

Inspired by this recent discussion on Hacker News (https://news.ycombinator.com/item?id=12448181) I'd like to ask if readers find the web page links below fast to load on their mobile phones?

I created the pages below as a test because I was (and still am) frustrated by the slow page loading speeds when using my phone on a patchy 3G connection.

I feel that many web developers don't realise that simple HTML and CSS is often all you need to make clear, fast loading pages. No complicated tricks or techniques required. You can make the page reasonably pleasant in appearance too.

Facebook has Instant Articles and Google has AMP (Accelerated Mobile Pages), but do we really need these approaches when we can accomplish fast loading pages with plain, uncomplicated HTML and CSS?

As I said, this was a test, nothing more. The page links below represent an article/blog/report style of page that is very common (and often slow to load) on the web.

Edit: just to add the content within these test pages are CC licensed and was used solely for the purpose of populated the page with real content. The pictures from the original synopsis are not included despite the references in the text.

So is it fast?

Here is an identical version to the above but one that loads custom fonts (approx 40kb extra). Is this slower?
