We check so you don't have to

Ionhour pings your endpoints from multiple regions around the world. A single slow region won't trigger a false alarm — only confirmed outages fire alerts.

  • Multi-region checks to avoid false alarms
  • Latency tracking and SSL expiry warnings
  • Custom headers, status codes, and response matching

Map your service dependencies

Model external services your app relies on — Stripe, Redis, Auth providers. When a dependency goes down, Ionhour automatically propagates a DEGRADED state to every service that depends on it.

  • Dedicated health probes per dependency
  • Automatic DEGRADED propagation across the graph
  • Blast-radius visibility before incidents escalate
