A CNAME at the zone apex can break MX and NS records. Use ALIAS/ANAME or A records instead.

Why this matters

CNAME at the apex (example.com) breaks every other apex record (MX, TXT, NS) — DNS-protocol violation per RFC 1034.

Learn more ▾

RFC 1034 forbids CNAME alongside other records at the same name. Some DNS providers offer ALIAS / ANAME / flattened-CNAME records that work around this — use those instead. Otherwise apex-level CNAME breaks email (no MX), domain ownership verification (no TXT), and more.

Source: RFC 1034

SPF helps prevent email spoofing. Add a TXT record starting with 'v=spf1'.

Why this matters

Without SPF, receiving servers can't validate sending IPs — your domain is easier to spoof in phishing.

Learn more ▾

SPF complements DMARC. Both should be published. SPF records list authorized sending IPs (e.g., `v=spf1 include:_spf.google.com ~all` for Google Workspace). After publishing, verify in Google Postmaster Tools or mxtoolbox.

Source: RFC 7208 (SPF)

B
DNSSEC
Unsigned (DNSSEC not deployed)
REVIEW
Unsigned (DNSSEC not deployed)
Info::
DNSSEC is not deployed
The zone is not DNSSEC-signed. Users on validating resolvers (Cloudflare 1.1.1.1, Quad9 9.9.9.9, growing default in mobile resolvers) get no protection against DNS spoofing for this domain. Most registrars now offer DNSSEC at a single click; consider enabling it for sites where authenticity matters (banking, healthcare, government).

CDN & Delivery
Action
Assets on AWS CloudFront (host cuatro.sim-cdn.nl, 79 assets); document served directly from origin
REVIEW
Assets on AWS CloudFront (host cuatro.sim-cdn.nl, 79 assets); document served directly from origin
Warning::
Document not behind existing CDN (AWS CloudFront serves the assets)
The page's subresources are delivered by AWS CloudFront (cuatro.sim-cdn.nl, 79 assets), but the HTML document itself comes straight from the origin. Routing the document through the CDN already in use is the cheapest latency win available here -- the provider relationship, the certificate and the config already exist. A short edge TTL with stale-while-revalidate suits HTML that changes often; if the response is genuinely per-user, edge TLS termination alone still removes a full round trip from every visitor's first byte.

Asset hosts on a CDN

  • cuatro.sim-cdn.nl — AWS CloudFront · assets: 79 · Cache Status: Hit from cloudfront
  • app.tolkie.nl — AWS CloudFront · assets: 3 · Cache Status: Hit from cloudfront
  • cdn-eu.readspeaker.com — CDN77 · assets: 3

  • fonts.bunny.net — assets: 2 · below probe threshold
  • cb.vrmwb.nl — assets: 1 · below probe threshold
  • www.vrmwb.nl — assets: 1 · below probe threshold

The heavy static files already ride an edge network, but every visitor still waits on the origin for the HTML itself. Routing the document through the same CDN is usually a config change rather than a migration: a short edge TTL with stale-while-revalidate for cacheable HTML, or edge TLS termination alone when the response is per-user.

B
CDN Cache Observability
No CDN cache-status headers in the response
REVIEW
No CDN cache-status headers in the response
Info::
No CDN cache-status headers in the response
Without an X-Cache / CF-Cache-Status / X-Vercel-Cache / Age header, you can't tell from outside whether a request hit the cache or went to origin. Operationally important: enables debugging stale-content reports and verifying cache rules. Most managed CDN platforms emit at least one of these by default; absence often means the platform's diagnostic headers are stripped at an upstream proxy.
B
Operational Status Page
No status page link detected
REVIEW
No status page link detected
Info::
No operational status page link detected
Status pages communicate planned maintenance and incidents to users -- a hallmark of operationally-mature services. Most SaaS teams publish one via Atlassian Statuspage, Instatus, BetterUptime, or a self-hosted Cachet. Smaller sites legitimately don't need one; flagged as Info, not a failure.
B
Health Check Endpoint
No conventional health endpoint found
REVIEW
No conventional health endpoint found
Info::
No conventional health endpoint found
Health endpoints (/health, /healthz, /status, /ping, /api/health) let uptime monitors, load balancers, and orchestration systems (Kubernetes, ECS, Fly.io) verify the service is alive. Marketing sites and small services often skip them legitimately; flagged as Info, not a failure. Probe results: /api/health: 404, /health: 404, /healthz: 404, /ping: 404, /status: 404.

Why this matters

robots.txt omits Sitemap: directive — crawlers must fetch /sitemap.xml by convention; reliable but missing the explicit hint.

The domain can be transferred without an unlock step. Enable registrar lock (clientTransferProhibited) in your registrar's control panel to protect against unauthorized or accidental transfers.

Why this matters

Without registrar lock, an attacker who phishes your registrar credentials can transfer the domain in minutes — total brand hijack.

Learn more ▾

Registrar lock (clientTransferProhibited, clientUpdateProhibited, clientDeleteProhibited) requires extra verification before any transfer/update/delete. Every major registrar offers it free. Combined with 2FA on your registrar account, it's the strongest defense against domain hijacking.
