This monitor verifies the external availability and responsiveness of our web platform by performing periodic health checks against the public-facing URL. It ensures that the platform is accessible to end users and functioning as expected from an external perspective. This check helps us detect potential outages, DNS resolution issues, SSL/TLS certificate problems, or network-level disruptions that may affect user access, even if internal services appear healthy. It serves as a critical indicator of real-world platform availability and user experience continuity.
