In January 2026, Alex Warner updated the Certificate Authority documentation in the cloudflare/cloudflare-docs repository to support Punycode domains. Working in Markdown and leveraging technical writing and documentation skills, Alex revised compatibility guidance to reflect recent SSL and GTS changes, removed outdated references to unsupported Punycode domains, and refreshed the compatibility check link. The update also reintroduced Punycode limitations based on product feedback, ensuring alignment with Product and Security teams. This targeted documentation change clarified onboarding for developers managing Punycode domains, reduced confusion, and improved trust and compatibility, though the scope was limited to a single feature without bug fixes.
