Priority fixes for udn.com

Ordered by impact and by how common each practice is among peers.

Priority 1 · Enable
XML sitemap discoverable
Observed: No sitemap was listed in robots.txt or found at /sitemap.xml.
Why it matters: A sitemap helps search engines find new and updated pages, especially on large or frequently updated sites.
What to do: Generate an XML sitemap of canonical URLs, reference it in robots.txt and submit it in Google Search Console.
87% of News & Media peers do this. Limit: Only the standard location was requested, once, at the time of the check.

Priority 2 · Accelerate
Static files cached for 30 days or more
Observed: A same-site stylesheet or script was cacheable for 8 days, short of the 30-day benchmark.
What to do: Give versioned (fingerprinted) CSS, JavaScript, fonts and images Cache-Control: public, max-age=31536000, immutable, and change the file name whenever the content changes.
60% of News & Media peers do this.

Priority 3 · Harden
HSTS kept for at least a year
Observed: The homepage response did not include a Strict-Transport-Security header.
What to do: Send Strict-Transport-Security on HTTPS responses. Start with a short max-age (for example 300 seconds), confirm every subdomain works over HTTPS, then raise it in steps to 31536000. Add includeSubDomains only when all subdomains are HTTPS. HSTS preload is optional and hard to undo; hstspreload.org itself does not recommend it by default.
35% of News & Media peers do this.

Priority 4 · Harden
DMARC policy enforces quarantine or reject
Observed: The DMARC policy for udn.com was p=none, which asks receivers to take no action on failing mail.
What to do: Publish DMARC with p=none and a reporting address first, fix any legitimate senders that fail SPF or DKIM alignment, then move to quarantine and finally reject.
37% of News & Media peers do this.
