Your client calls about the SSL warning.
You should have known three weeks ago.
Web development agencies are accountable for infrastructure long after the project closes. SSL certificates, DNS records, and hosting vendor status don't come with maintenance contracts — but client expectations do. Merlonix watches everything so you don't have to remember to.

Where web development agencies get surprised
Infrastructure you built but don't own — and still get blamed for.
Web development agencies exist in an uncomfortable middle ground: you configured the infrastructure at launch, the client owns it now, but your name is first in the support call when something breaks. SSL expiry, DNS errors, and hosting outages are silent until they aren't.
Post-launch SSL drift
Certificates expire on sites you handed off months ago
Let's Encrypt auto-renewal works until it doesn't. A hosting migration, a DNS change, or a CAA record conflict silently breaks renewal. The first indication is a browser warning — usually reported by the client, not caught by your team. By then the SEO damage and trust erosion are already underway.
DNS fragility after migrations
Every handover creates DNS drift risk
Domain transfers, registrar switches, CDN migrations, and subdomain additions each carry DNS misconfiguration risk. A misplaced CNAME, a missing MX record, or a TTL set too high after a migration can render parts of the site unreachable — without any HTTP-level indicator your ping monitor can catch.
Hosting vendor dependency
Your client's site depends on infrastructure you don't control
Vercel, Netlify, Cloudflare, AWS, GitHub Pages — every deployment platform has outages. When the hosting vendor goes down, the site goes down, and the client calls the agency. Merlonix monitors 11 major vendor status pages so you can respond with context before you even receive the first message.
How it works
Every client site. One place. One alert when something breaks.
Merlonix is built for agencies managing portfolios — not individual site owners checking a single domain. The multi-tenant model lets you cover 10 or 200 client sites from the same account without billing complexity.
01
Add each client site once
Verify domain ownership with a DNS TXT record or .well-known file — one attestation per domain, covering all subdomains you monitor under it. Takes under two minutes per client.
02
SSL and DNS checked continuously
Certificates are validated end-to-end — issuer, chain completeness, key algorithm, and expiry date — not just port-443 reachability. DNS is checked against three independent resolvers. Discrepancies surface immediately.
03
Hosting vendor incidents tracked automatically
Vercel, Netlify, Cloudflare, AWS, GitHub, and six more hosting-adjacent vendors are polled every five minutes. Incident opens, you know. Incident resolves, you know. No manual status page checking.
04
Alerts go to Slack, Teams, or email
Every alert includes the domain, the check type, and the current state — enough context to respond before opening a browser. Route critical alerts to on-call channels; route informational alerts to a digest.
What the coverage means for web agencies
From reactive firefighting to proactive client trust.
Web development agencies that monitor proactively have a different kind of client conversation. Instead of explaining why a site was down for four hours, they're sending a message at 2am saying they caught it before any end users were affected. That difference is the foundation of a retainer relationship.
