Static sites still have DNS and SSL surface
that standard monitoring misses.
Gatsby agencies deploy client sites as static outputs to Netlify, Vercel, or Cloudflare Pages — each with a CNAME delegation from the client's custom domain to the CDN edge. When clients change registrars, move DNS to Cloudflare, or switch IT providers, CNAME records break silently. The build succeeds. The site deploys. The DNS record points nowhere. Merlonix catches the break before clients report it.

Where Gatsby agencies get caught out
Three failure modes specific to Gatsby static site deployments.
Static sites have the same DNS and SSL attack surface as dynamic sites — they just break silently because there is no server error to surface the problem. Gatsby agencies managing client portfolios across Netlify, Vercel, and Cloudflare Pages need DNS and SSL monitoring that standard tools don't provide.
CDN CNAME drift after client DNS migrations
Client registrar migrations break static site CNAME delegations without any build-side indication
Gatsby agencies configure custom domains by adding a CNAME record in the client's DNS zone pointing to the CDN edge — Netlify, Vercel, or Cloudflare Pages each have their own CNAME target. When a client migrates their domain to a new registrar, the DNS records are frequently carried over incompletely. The CNAME record is the most common casualty: it is often dropped, recreated with the wrong target, or created at the apex zone instead of the subdomain level. The Gatsby build process and the CDN platform have no visibility into whether the client's DNS is correctly pointing at them. The site deploys, the build log shows success, and the DNS break is invisible until a client or end user reports the site is offline.
SSL certificate reprovisioning gaps
Static site CDN platforms reprovision SSL on their schedule after CNAME changes
Netlify, Vercel, and Cloudflare Pages provision SSL certificates for custom domains automatically via Let's Encrypt. Certificate provisioning requires that the CNAME record is intact and correctly resolving. When a client CNAME breaks, the CDN platform cannot reprovision the certificate at the next renewal cycle because the ACME DNS challenge fails. The existing certificate stays valid and shows as "healthy" in any SSL checker until the renewal deadline passes — then the custom domain goes HTTPS-broken with no advance warning to the agency. For certificates renewed 6–8 months ago, the gap between the CNAME breaking and the SSL failure is invisible to standard monitoring.
Multi-CDN portfolio complexity
Gatsby agencies using Netlify, Vercel, and Cloudflare Pages simultaneously have no unified DNS view
Gatsby agencies managing 10–30 clients rarely use a single CDN for every client. Some clients come with an existing Netlify account. Others are hosted on Vercel because a previous developer set it up. Some moved to Cloudflare Pages for performance or cost reasons. Each CDN platform has its own CNAME target format, custom domain configuration interface, and DNS validation approach. Managing DNS health across three CDN platforms with 10+ clients each requires checking three dashboards. Merlonix gives agencies a single view of CNAME integrity and SSL health across all CDN platforms in one place.
How it works
SSL and DNS monitoring across every CDN your Gatsby clients use.
Merlonix monitors CNAME integrity and SSL health across Netlify, Vercel, and Cloudflare Pages deployments from a single dashboard — so Gatsby agencies get one view instead of three CDN dashboards with no DNS visibility.
01
Add client domains in under two minutes each
Verify ownership with a DNS TXT record on the apex domain. All subdomains — production, staging, and branch deploy custom domains — are added without additional verification. Full monitoring coverage starts immediately, regardless of which CDN each client uses.
02
CNAME integrity checks across all CDN platforms
Three independent DNS resolvers verify CNAME records on every check interval — whether the target is a Netlify, Vercel, or Cloudflare Pages endpoint. When a client nameserver migration drops a CNAME, the alert fires within minutes, while the current SSL certificate is still valid and there is still time to restore the record before any visitor impact.
03
SSL chain validation and domain expiry
Full SSL certificate chain validation on every check. Expiry alerts at 30 days lead time. Domain registration expiry alerts separate from SSL expiry. A client who forgot to renew their domain registration gets a 30-day warning — not a site-offline call at midnight.
04
Vendor status for Netlify, Vercel, and Cloudflare
Merlonix monitors Netlify, Vercel, and Cloudflare platform status alongside client SSL and DNS. When a Netlify CDN degradation takes multiple client sites offline simultaneously, you see the vendor incident before clients start reporting — and the correlation is automatic, not manual.
What the numbers mean for Gatsby agencies
Monitoring built for multi-CDN static site portfolios.
Gatsby agencies deploying client sites across Netlify, Vercel, and Cloudflare Pages have DNS and SSL surface spread across three CDN platforms with no single visibility layer. Merlonix consolidates CNAME and SSL monitoring across all three into one dashboard with per-client alert routing.
< 10 min
Time from DNS change to alert — catches CDN CNAME drift before the SSL certificate enters its renewal window
30 days
SSL expiry warning lead time — enough time to restore a broken Netlify or Vercel CNAME before certificate renewal fails
