I put in my site and it gave me a red cross for "Hosting", on hover it said "GitHub Pages". But my site isn't hosted on GitHub Pages.

Expanding "Details", the URL that is hosted on GitHub Pages is... a different website? There's merely a hyperlink to it on my website.

It also says I'm using "self-hosted" fonts - but I don't think I'm doing that at all? I'm just using the browser's fonts. Using non-standard fonts is a bad idea because it causes the content to either be invisible until the font is loaded, or else it initially shows in a fallback font and then the text all jumps when the font is loaded.

It also says my website is hosted on GitHub pages, although it’s served from a hetzner server.

EDIT: on further inspection: I get both a red cross AND a green check mark for hosting. So it’s somehow indicating both GitHub and hetzner. Maybe it’s because I merely link to GitHub?

Thanks for the Bugs Bunny. I'm detecting a LINK to GitHub Pages and marking it as hosting. That's wrong - hosting should only flag when the actual page is served from there.

Re fonts: "self-hosted" means fonts served from your domain (vs Google Fonts CDN). If you're using system fonts, that's a detection error on my end.

Both going in on the fix list. Thanks.

Meanwhile I get a green check for CDN - presumably because I'm not using Cloudflare, but I am using CloudFront which is AWS.

So the tool's a good idea, but currently very inaccurate.

Meanwhile, mine is actually hosted on GH pages and I get a green mark and a perfect 100% score.

Funny, I checked a blog I host on github pages and it says "not detected" for hosting.
