If there’s connection one thing I’d like readers to take away from this post it’s that font-display: swap is a very good option for users with a fast internet. But its infinite swap period could be frustrating for users on very slow and unstable connections. If you have users viewing your site under these conditions (I’m pretty certain you will at some point in time), then it may be worth considering font-display: fallback or even font-display: optional. Both have a short swap period (or no swap period), meaning once the fallback font is rendered and the 3 second timeout is exceeded, the font won’t change for the rest of the page lifecycle.
