nirn-probe

GitHub

Cloudflare ban probe for Discord edges with Prometheus metrics for fleet health.

Go Prometheus

nirn-probe monitors edge health for Discord connections and exports Prometheus metrics for dashboards and alerting.

Why It Exists

Discord routes traffic through Cloudflare, and sometimes specific edge locations get your IPs flagged or banned. When that happens, connections from certain regions start failing while others work fine. Without visibility into which edges are healthy, debugging becomes guesswork.

How It Works

nirn-probe continuously probes Discord's edge servers and tracks:

  • → Connection success rates: Which edges accept connections vs. reject or timeout
  • → Latency distribution: P50/P95/P99 latencies per edge location
  • → Ban detection: Identifies when Cloudflare is blocking your traffic

Integration

Pairs naturally with nirn-proxy. Use probe metrics to alert on edge health degradation, then route traffic away from problematic edges at the proxy layer.
