Priority fixes for ais.th

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

1. Priority 1 · Harden

   DMARC policy enforces quarantine or reject

   Observed: No DMARC record was found at _dmarc.ais.th.

   Why it matters: An enforcing DMARC policy helps receiving mail systems reject email that falsely claims to come from your domain, a common route for phishing your customers.

   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.

   59% of Telecommunications & Internet peers do this. Limit: Read from public DNS at the time of the check; records may have changed since.

2. Priority 2 · Accelerate

   Modern image formats in use

   Observed: The homepage had 77 images and none used WebP or AVIF.

   What to do: Serve WebP or AVIF with a JPEG or PNG fallback, either through an image CDN or by generating both formats at build time.

   On Cloudflare: Cloudflare Polish can convert images to WebP.

   52% of Telecommunications & Internet peers do this.

3. Priority 3 · Accelerate

   Static files cached for 30 days or more

   Observed: A same-site stylesheet or script was cacheable for 1 hours, 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.

   On Cloudflare: Use Cache Rules to set edge and browser TTLs for static file paths.

   41% of Telecommunications & Internet peers do this.

4. Priority 4 · Accelerate

   Offscreen images lazy-loaded

   Observed: The homepage had 77 images and none used loading="lazy".

   What to do: Add loading="lazy" to images below the fold. Do not lazy-load the main hero image, because that delays the largest visible element.

   66% of Telecommunications & Internet peers do this.
