Priority fixes for carbu.com

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

Priority 1 · Accelerate
HTTP/2 negotiated
Observed: The TLS handshake selected HTTP/1.1 instead of HTTP/2.
Why it matters: HTTP/2 sends many files over one connection, which speeds up pages with lots of images, styles and scripts.
What to do: Enable HTTP/2 on your CDN or server. Most CDNs do this by default.
72% of Energy, Electricity & Gas peers do this. Limit: Certificate and protocol were observed from one vantage point; CDNs can present different certificates by region.

Priority 2 · Harden
TLS 1.3 negotiated
Observed: The TLS connection negotiated TLSv1.2.
What to do: Enable TLS 1.3 on your CDN or server. Keep TLS 1.2 available for older clients unless you have checked your audience.
86% of Energy, Electricity & Gas peers do this.
Guide: HTTPS and TLS Guide for Website Owners
Priority 3 · Harden
DMARC policy enforces quarantine or reject
Observed: The DMARC policy for carbu.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.
64% of Energy, Electricity & Gas peers do this.

XML sitemap discoverable
Observed: No sitemap was listed in robots.txt or found at /sitemap.xml.
