If you are experiencing outdated content or outdated styling, the cause might be the use of a custom domain with Cloudflare Pages. While a deployment in Cloudflare Pages automatically purges caches on pages.dev, and apparently also on custom domains if there are no page rules or cache settings configured,¹ I have had it happen that styles were still outdated.

As documented by Cloudflare, manually purging the caches might be necessary. Go to the Cloudflare dashboard, select your domain, go to "Caching", "Configuration" and then click on "Purge Everything". After a final confirmation, you should see your updated content.
