Ahrefs reports 2,357 pages with "broken JavaScript" because the external umami.padelnomics.io/Z.js returns HTTP 525 (Cloudflare SSL handshake failure). Self-host the script as a static file and use data-host-url so analytics POSTs still reach the Umami instance. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
