Priority fixes for zoom.earth
Ordered by impact and by how common each practice is among peers.
Priority 1 · Harden
DMARC policy enforces quarantine or reject
Observed: The DMARC policy for zoom.earth was p=none, which asks receivers to take no action on failing mail.
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.
31% of Weather Forecast peers do this. Limit: Read from public DNS at the time of the check; records may have changed since.
Priority 2 · Enable
Canonical URL declared
Observed: The homepage did not declare a canonical URL.
What to do: Add a self-referencing canonical link to every indexable page, using the final https:// URL.
61% of Weather Forecast peers do this.
Priority 3 · Accelerate
HTTP/3 advertised
Observed: The homepage did not advertise HTTP/3 through an Alt-Svc header.
What to do: Turn on HTTP/3 at your CDN. Browsers fall back to HTTP/2 automatically, so the risk is low.
On Cloudflare: Enable HTTP/3 (with QUIC) under Speed > Optimization > Protocol Optimization.
28% of Weather Forecast peers do this.
Priority 4 · Harden
Content Security Policy present
Observed: The homepage response did not include a Content-Security-Policy header.
What to do: Start with Content-Security-Policy-Report-Only to see what would break, tighten the policy over a few weeks, then enforce it.
22% of Weather Forecast peers do this.
