Updated Apr 8, 2026

Toggle the symptoms you're observing — signal degradation, packet loss, session drops, DNS failures, time-of-day patterns, and more — to get a ranked list of probable root causes with diagnostic steps. No guesswork, no ML: pure deterministic logic built from real-world cellular WAN failure patterns.

Covers 7 cause categories: RF Degradation, Carrier Congestion, DNS Dependency, NAT Timeout / Tunnel Instability, Carrier Core / Routing, Failover Misconfiguration, and SIM / Device issues. Each result includes a rationale sentence and numbered diagnostic steps ordered by impact. Designed for financial branch engineers diagnosing LTE/5G WAN incidents under time pressure.

Outage Pattern Classifier

Select the symptoms you observed during the outage. The classifier will rank likely cause categories and suggest next diagnostic steps.

Signal & Loss Symptoms

Latency spikes observed (periodic high RTT, not constant)Packet loss presentComplete outage periods (total loss of connectivity)Weather correlation (symptoms worse during rain, wind, or storms)SIM-specific (only this SIM/device affected; other SIMs on same tower are fine)

Application Layer Symptoms

DNS failures observed (failed hostname resolution)VPN tunnel resets (tunnel drops and renegotiates)

Pattern Symptoms

Time-of-day pattern (symptoms worse at specific hours)Affects all sites equally (multiple branches showing same symptoms simultaneously)Failover triggered (WAN failover activated during the event)

0 symptoms selected — select at least 2 to classify
