Traditional uptime monitoring just checks if a server responds. We specifically monitor HTTP status codes, which means we catch issues like 404 errors, redirects, and server errors that uptime tools might miss.
Currently, we monitor publicly accessible URLs. For password-protected pages, we recommend monitoring your login page or using our Core Web Vitals monitoring for authenticated performance testing.
