Fonts disappearing is not a big issue that will ultimately render your page useless. If the font is gone, the look of the page is slightly affected, but the content of the page remains. It's honestly not a big deal at all.

In that case just use sans-serif or a web-safe font and avoid the third-party dependency.

Here as we enter the 2020s, there are no longer any web safe fonts. Those 1990s Core Fonts for the Web (Verdana, Georgia, Trebuchet, etc.) are no longer universal across all widely used platforms.
