Public CDNs Are Useless and Dangerous

So here you get the worst of both on a slow connection.

- The page takes an extra 100ms to load

- ~ a minute later (when you're halfway through reading it) the content will jump by some large amount.

There isn't a nice way to do custom fonts on the web and you should just avoid them.

Sorry, no part of your comment is true. This is easily the best option for slow connection/device users, and it comes at the expense of the design.

> The page takes an extra 100ms to load

Nope. Slow connections' floor for first paint is 100ms when using `font-display: optional` – not an additional 100ms. The page is still loading like normal in this period. (If you're already under a 100ms FCP for 3G users, you know all of this already)

> the content will jump by some large amount

`font-display: optional` is literally designed to prevent this from ever occurring. Either the font is ready for first paint in 100ms, or another font is used.
