Path analysis

Traffic changed route while latency was elevated. A reroute of this kind usually follows a fault somewhere on the original path.

Cross-probe verdict. Too few independent vantage points were watching this endpoint to reach a cross-probe verdict.

Detection method

Latency is sampled continuously from our probe network. An alert opens when round-trip time to a monitored endpoint holds above its rolling baseline, and closes automatically once it returns. Full method is described on the methodology page.
