Internet Outage Detector​

Detect Internet Outages


Ever wondered why your video calls sometimes suffer from poor voice/video quality? It may be related to reliability (not bandwidth) of your Internet connection.

We had this problem in my company for a while, main difficulty was that it happened only rarely. This project helps to detect Internet outages over a long period of time (e.g. 1 month) with minimal footprint.


It uses iperf3 running in special mode using minimal bandwidth so your other activities are not affected by the test.

It helped us to detect defective Wi-Fi router and find out reliability of our Internet provider (99.98%).


Following projects are used:


  • iperf3 tool for active measurements of the maximum achievable bandwidth on IP networks
