How Huginn Detected a Silent Switch Failure at a 400-Room Resort

The Problem Nobody Saw

A 400-room Mediterranean resort was receiving increasing guest complaints about slow Wi-Fi. The network vendor dashboard showed 99.8% uptime. Everything looked fine — except to the guests.

Enter Huginn

The property deployed Huginn monitoring probes across three floors. Within 48 hours, the data told a different story:

  • Packet loss:2-4% on the east wing core switch

  • Latency spikes:200ms+ every 3-4 minutes during peak hours

  • DNS resolution:Intermittent failures averaging 8 per hour

The Root Cause

Huginn pinpointed a core switch with a failing ASIC. The vendor monitoring was measuring interface counters, not actual data plane performance.

The Lesson

Trust, but verify. Your vendor tools are designed to show their equipment working. Independent monitoring shows your network working from the guest perspective.
