The “crossorigin” conundrum

After days of getting results that I shouldn’t be getting, I’m sending up an SOS to anyone who can set me straight.


Note: Please see the Updates at the end.

One thing you’ll often see explained on the web is that, if you preload a web font to enhance your site’s performance, the preload statement must include crossorigin or the font will be double-downloaded.

But what if you include crossorigin and the font still is downloaded twice?

That’s an oddity I’ve been experiencing, and I hope somebody reading this will have the answer; because, for days, I’ve tried in vain to figure this out. Given the following HTML (formatted here for easier reading):


. . . and the following within the CSS:

@font-face {
	font-family: 'Inter';
	font-weight: 1 999;
	font-style: normal;
	font-display: swap;
	src: url('/fonts/Inter-3-19_subset_2021-06-18.woff2') format('woff2-variations'), url('/fonts/Inter-3-19_subset_2021-06-18.woff2') format('woff2');
	unicode-range: U+0000-00FF, U+0131, U+0152-0153, U+02BB-02BC, U+02C6, U+02DA, U+02DC, U+2000-206F, U+2074, U+20AC, U+2122, U+2191, U+2193, U+2212, U+2215, U+FEFF, U+FFFD;

. . . I don’t understand why I get this result (this is a “waterfall” from GTmetrix):

Screen capture of “waterfall” data from a GTmetrix test of this website’s home page

. . . which shows that the woff2 font file is loaded twice.

(And I’ve tried different fonts, each of which double-loads when I employ similar code, so it’s not anything about the specific font file shown above.)

Help, please?? Thanks in advance.

  • In the initial publication of this post, I neglected to mention that, specifically due to the problem described herein, the site at that time didn’t use web fonts—so I apologize to anyone who went looking through the source code for them while trying to answer my question.
  • It now appears this issue is specific to the site’s current host, Cloudflare Pages. However, I will leave this post in place for the sake of transparency.
