Monitoring Strikingly Client Sites for Agencies: SSL, DNS, and Platform Failures
Strikingly is a website builder popular for simple landing pages, product launch sites, and business presence pages — particularly for clients who want a clean, mobile-optimized site without a technical team. Agencies building on Strikingly manage the setup and ongoing maintenance, but the infrastructure monitoring gap is real: SSL provisioning stalls, DNS drift after client nameserver changes, and platform incidents with no public status page create failure modes that agencies discover from client calls rather than from monitoring alerts.
This post covers the specific failure patterns that affect Strikingly agency client portfolios and the monitoring setup that catches them before clients notice.
How Strikingly Handles SSL and Custom Domains
Strikingly provisions SSL for custom domains through a CNAME-based verification process. When a client connects a custom domain to their Strikingly site, the agency adds a CNAME record in the client's DNS pointing to Strikingly's CDN infrastructure. Strikingly verifies the CNAME, then issues and manages the SSL certificate.
The process works when conditions are ideal: CNAME propagated fully before Strikingly's provisioning system checks, DNS records stable after setup, and the client's registrar or DNS provider maintaining the CNAME correctly. When any of those conditions change, the SSL provisioning or renewal breaks — and the failure is often invisible until it affects visitors.
The Failure Modes to Watch
1. SSL provisioning stalls when CNAME is incomplete at activation
Strikingly's SSL provisioning runs when the agency initiates the custom domain connection. If DNS propagation is incomplete at that moment — which is common when agencies set up custom domains close to the client's launch deadline — the CNAME verification fails and SSL provisioning enters a stalled state.
The stall is not always visually obvious in the Strikingly dashboard. The domain may show a "pending" status that persists until the agency investigates. In some cases, the site continues to load over HTTP while SSL provisioning remains stuck, and the agency doesn't notice until a visitor reports the "not secure" indicator in their browser.
What to monitor: SSL certificate status and chain validity from the moment the custom domain is connected. A missing or invalid certificate on a Strikingly custom domain after the expected propagation window (usually 24–48 hours) indicates a provisioning stall that needs investigation.
2. Client nameserver changes break the Strikingly CNAME silently
Clients change their DNS configuration for reasons unrelated to the Strikingly site: migrating email hosting, switching registrars for a better renewal price, consolidating domains under a new DNS provider after a business change. When the nameserver changes, the CNAME record pointing to Strikingly's CDN needs to be recreated at the new provider.
This step is frequently missed. The old DNS provider's CNAME is no longer authoritative. The Strikingly CDN no longer receives requests for the custom domain. Visitors see a DNS resolution failure — or, worse, a DNS lookup that resolves to the previous hosting provider's default page.
The failure is masked by browser cache for existing visitors. New visitors and visitors with empty caches encounter the failure immediately. The agency typically learns about it when a new visitor — a prospect, a client's new employee, a reporter — mentions that the site isn't loading.
What to monitor: CNAME record integrity for every Strikingly custom domain, verified by multiple independent DNS resolvers on each check interval. Any change to the CNAME target fires an alert immediately.
3. Strikingly platform incidents affecting the entire client portfolio
Strikingly does not maintain a public status page with real-time incident data. When Strikingly's CDN experiences degradation, a platform deployment causes issues, or their SSL provisioning infrastructure encounters a problem, agencies have no upstream signal.
The practical effect: when a Strikingly platform incident causes multiple client sites to fail simultaneously, the agency diagnoses each site independently before identifying the common cause. Client calls compound. The agency is reactive rather than proactive, and there is no accurate timeline to communicate to clients because the incident status is invisible.
What to monitor: Strikingly platform status through external monitoring. When platform incidents occur alongside per-domain failures, the upstream cause becomes visible immediately rather than after manual investigation.
4. Domain expiry on client-owned registrars
Clients who manage their own domain registrar accounts sometimes let domains expire — particularly if renewal notices go to an email address that has changed, if billing contact information is out of date, or if the domain was registered by a previous vendor whose contact information is still on file. The Strikingly site disappears completely when the domain expires, and the agency is not in the notification path.
What to monitor: Domain expiry approaching within 30 days, tracked separately from SSL expiry. The 30-day lead time is usually enough to prompt the client to renew before the site goes dark.
What a Strikingly Monitoring Setup Looks Like
An effective monitoring setup for a Strikingly agency portfolio covers four layers:
SSL certificate monitoring: Validates full chain status — expiry date, issuer, chain completeness, and domain match — on every check interval. Fires at 30 days before expiry and immediately on any certificate change or chain break.
DNS record monitoring: Watches the CNAME record pointing to Strikingly's CDN for each custom domain. Fires immediately on any CNAME change, regardless of whether the change causes immediate downtime. Catches post-nameserver-migration drift before visitors encounter failures.
HTTP uptime monitoring: Basic availability check for the Strikingly site. Catches full outages, redirect failures, and configuration errors that prevent the site from serving responses.
Vendor status monitoring: Tracks Strikingly platform status externally. When a Strikingly infrastructure incident is responsible for multiple client sites failing, the cause is surfaced in the alert feed rather than discovered after diagnosing several clients independently.
Why Standard Uptime Tools Miss Strikingly Failures
Strikingly failures share a characteristic with most website builder failures: they occur at the DNS and certificate layer, not the HTTP layer. An uptime tool checking the Strikingly site URL and verifying a 200 response will:
- Report green when the CNAME has broken but browser-cached DNS still resolves for returning visitors
- Not detect an SSL provisioning stall until the certificate expires and the site starts serving HTTP
- Not alert when a client nameserver migration has broken the CNAME that the next SSL renewal depends on
- Provide no information about whether a multi-client failure is a Strikingly platform incident or a per-domain configuration issue
Agencies using HTTP-only uptime monitoring on Strikingly client sites have a gap between what the monitor reports and what new visitors experience. External DNS and SSL monitoring closes that gap.
How Merlonix Covers Strikingly Client Sites
Merlonix is designed for agencies managing client portfolios across website builders and CMS platforms. Adding a Strikingly client domain takes under two minutes: DNS TXT record verification, then SSL and DNS monitoring starts automatically.
Each client's domains are organized under their client account. When CNAME drift is detected after a nameserver change, the alert fires within minutes — with the previous and current record values included. When a Strikingly platform incident is active, the vendor status feed surfaces it separately from per-domain alerts.
