Checklist
Website Uptime Monitoring Checklist
What to monitor
Monitor the homepage, login page, checkout or booking flow, public API status, and any customer-facing app routes that directly affect revenue.
How often to check
For critical systems, start with 1-minute checks. Client brochure sites can often use 5-minute checks, but production SaaS endpoints deserve faster visibility.
What alerts to create
Create alerts for downtime, repeated degraded latency, failed status codes, SSL warnings, and domain expiry windows.
What to do when a site goes down
Confirm from multiple regions, check recent deploys, look at provider status pages, notify stakeholders, and log the incident timeline.
