Wix custom domains break SSL.
Your client finds out first.
When a Wix client connects a custom domain through their own DNS provider, Wix-managed SSL provisioning can fail silently. The site returns a 200 OK while browsers show a certificate warning. Merlonix monitors the infrastructure layer your uptime tool skips — so you know before the client's visitors do.

Where Wix agencies get caught out
Three failure modes specific to Wix client portfolios.
Uptime monitors check HTTP response codes. The Wix-specific failures — SSL during custom domain connection, DNS after a registrar transfer, and upstream platform incidents — all fail at a layer below HTTP. They're the failures that generate client calls.
Custom domain connection
Wix SSL breaks when clients use external DNS
When a Wix client points their custom domain using external nameservers instead of Wix's nameservers, Wix's automatic SSL provisioning can stall or fail silently. The domain resolves, the site loads, and a certificate warning appears in some browsers — while your uptime monitor reports green.
DNS configuration opacity
Wix DNS settings are hard to audit
Wix manages DNS differently depending on whether the client uses Wix nameservers or points an external domain. When clients switch between these modes — or when a domain is transferred to a new registrar — the DNS configuration can drift from the expected state without any obvious signal.
Platform dependency
Wix platform incidents affect all your client sites
A Wix infrastructure incident — CDN degradation, authentication service issues, media serving problems — can affect dozens of client sites simultaneously. Your uptime monitor might catch a full outage, but partial degradations and regional incidents often go undetected until clients call.
How it works
Set up once per client. Watch every domain from there.
Merlonix is designed for Wix Studio agencies managing client rosters across multiple domain configurations — one account, every domain, one alert flow that only fires when something actually needs attention.
01
Add your Wix client domains
Verify ownership with a DNS TXT record — Merlonix supports both Wix-nameserver domains and externally pointed domains. One attestation per domain establishes the monitoring baseline. Takes under two minutes per client.
02
SSL and DNS checked every 5 minutes
Three independent DNS resolvers verify your expected records on every check interval. SSL chains are validated end-to-end: expiry date, issuer, chain completeness, and domain match. Wix custom domain connections are monitored continuously — catching provisioning failures before they reach the browser.
03
AI separates Wix DNS noise from real problems
Wix DNS configurations can produce transient resolution anomalies during propagation that would fire false positives on simpler monitors. Merlonix classifies each DNS change — transient propagation versus genuine drift — so you are not paged for a record that resolves correctly five minutes later.
04
Alert goes to Slack or email, not a dashboard
Alerts include domain, check type, the specific record or certificate field that changed, and recommended action. No login required to triage. No additional tab to monitor between client calls.
What the numbers mean for Wix agencies
Monitoring that covers the Wix-specific failure surface.
Wix Studio agencies don't have a dedicated infrastructure team. You have designers and developers who also handle domain connections and client handoffs. Merlonix is built around that constraint — minimal setup, maximum signal, zero dashboards to babysit between client calls.
