# Blackbox Exporter

### An active network probing tool that validates the external reachability and DNS health of all critical service endpoints.

**Blackbox Exporter monitors the active availability and network health of our decoupled architecture.** It continuously probes the Drupal backend, static site delivery, and Model Context Protocol (MCP) services over HTTP/TCP, instantly feeding uptime metrics to Prometheus to detect and alert on container failures before users are affected.

### Active Endpoint Probing

In a highly distributed system like SCORE Cloud, verifying that services are reachable from the outside is just as critical as internal resource monitoring. Blackbox Exporter acts as the frontline network probe within the observability stack, performing active network polling against infrastructure nodes to guarantee decoupled Progressive Web Apps remain highly responsive.

**Ready to elevate your brand with scalable and secure cloud solutions?** Let’s create a foundation tailored to your growth and designed to deliver impactful results.
