Priority fixes for sky.com

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

Priority 1 · Accelerate
Static files cached for 30 days or more
Observed: A same-site stylesheet or script was cacheable for 1 days, short of the 30-day benchmark.
Why it matters: Returning visitors and later page views reuse cached files instead of downloading them again.
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.
41% of Telecommunications & Internet peers do this. Limit: Read from the homepage response only; other pages or regions may send different headers.
Guide: Browser Caching Guide for Website Owners
Priority 2 · Enable
Social preview image set
Observed: The homepage had no og:image, so shared links may show without a preview image.
What to do: Add Open Graph tags, including og:image with a 1200 x 630 image.
59% of Telecommunications & Internet peers do this.

Priority 3 · Harden
CAA records limit who can issue certificates
Observed: No CAA record was found for sky.com, so any public certificate authority may issue for it.
What to do: Publish CAA records naming every CA you actually use, including the CAs your CDN uses for managed certificates. Add an iodef contact if you want reports.
15% of Telecommunications & Internet peers do this.
Guide: HTTPS and TLS Guide for Website Owners
Priority 4 · Harden
security.txt published
Observed: No valid /.well-known/security.txt with a Contact field was returned.
What to do: Publish /.well-known/security.txt with at least Contact and Expires fields, as RFC 9116 requires, and review it before it expires.
13% of Telecommunications & Internet peers do this.
