Squarespace manages hosting.
You still own the domains.
Squarespace provisions SSL automatically — until a client changes their DNS, migrates to a new plan, or connects a custom subdomain. At that point, provisioning depends on DNS propagating cleanly, and when it doesn't, the failure is invisible to a ping monitor. Merlonix watches that gap.

Where Squarespace agencies get caught out
Three failure modes at the edge of what Squarespace manages.
Squarespace handles infrastructure for you — until the edge of its platform. Custom domain SSL, DNS during migrations, and upstream payment processing all live in your operational responsibility zone, not Squarespace's.
DNS dependency
Custom domain SSL provisioning fails quietly
Squarespace automates SSL for its subdomains. For custom domains, the certificate is provisioned only after DNS propagates correctly. A registrar delay, a partial CNAME update, or a misconfigured AAAA record can block provisioning — and the site returns a browser warning while your uptime monitor shows 200 OK.
Platform migration
Moving clients from Squarespace leaves DNS debris
When a client outgrows Squarespace or moves to a new platform, DNS records need to be re-pointed and old entries cleaned up. CNAME records referencing Squarespace infrastructure, outdated MX records, and stale SPF entries all create failure windows. Merlonix alerts on the specific record that diverged.
Commerce dependency
Stripe and Afterpay outages hit Squarespace Commerce
Squarespace Commerce depends on Stripe for payment processing. Extended Stripe incidents mean clients cannot complete purchases. Merlonix monitors Stripe, PayPal, and other upstream vendors so you know before the client calls about abandoned carts.
How it works
Set up once per client. Watch every migration from there.
Merlonix is designed for agencies managing many Squarespace clients — one account, every domain, one alert flow that only fires when something actually needs attention.
01
Add your Squarespace client domains
Verify ownership with a DNS TXT record or .well-known file — one attestation per domain. Works whether you manage the client DNS or they do. Takes under two minutes per domain.
02
SSL and DNS checked every 5 minutes
Three independent DNS resolvers validate expected records on every check. SSL certificates are checked end-to-end — expiry date, issuer identity, chain completeness, and domain match against Squarespace provisioned certs.
03
AI classifies changes before alerting
DNS propagation during a Squarespace domain connection can look like drift to a naive monitor. Merlonix classifies each change against expected propagation patterns and only alerts on genuine issues — not transient resolver disagreements.
04
Alert delivered to Slack or email
Alerts include the specific certificate field or DNS record that changed, the domain, and recommended action. No login required to triage. Enough context to act without opening a browser.
What the numbers mean for Squarespace agencies
Monitoring built around what Squarespace doesn't cover.
Squarespace agencies don't need infrastructure operations. But they do need visibility into the failure modes that Squarespace's own status dashboard won't surface — custom domain SSL health, client DNS state, and upstream payment vendor incidents.
30 days
SSL expiry warning lead time — enough runway to fix before the client sees a browser warning
< 10 min
Time from DNS change to alert — covers the critical DNS propagation window on platform migrations
11 vendors
Upstream services monitored — including Stripe, the payment backbone for Squarespace Commerce
200 assets
Maximum monitored domains on the Agency plan — enough for a full Squarespace client roster
