External Health Checks with Failior for Early API and Domain Outage Detection

The Importance of External Health Checks

Monitoring public-facing APIs and domains only through internal telemetry or user reports can delay identifying outages or degraded performance. External health checks simulate real user interactions by querying your endpoints from outside your network. This offers an independent view of service availability and correctness.

Failior automates these external polls on a schedule you set. It alerts your team on failures such as no response, increased latency, or invalid data. This gives you a chance to act before customers experience problems.

• Provides an independent, external perspective on API and domain health.
• Detects downtime and incorrect or unexpected responses promptly.
• Helps reduce mean time to detection (MTTD) by alerting before customer impact.
• Supports uptime monitoring across multiple endpoints and public-facing services.

How Failior External Health Checks Work

With Failior, you define monitors that periodically reach out to any public API or domain. You specify what a healthy response looks like, including expected status codes, response time limits, and key response content.

Alerts trigger if an endpoint is unreachable, slow, or returns unexpected data. This external perspective complements Failior's internal instrumentation tools, giving a full picture of system health.

• Simple setup through Failior's monitoring platform with minimal configuration.
• Supports custom API requests, status code verification, response content checks, and domain resolution tests.
• Integrates with Failior alerting for webhooks, email, and phone escalations depending on plan.
• Provides historical records and trends to analyze incident patterns and improve reliability.
• Works alongside Failior dependency graphs and browser RUM for end-to-end visibility.
