Path analysis
Traffic kept the same route. Latency rose without a visible path change, which points at congestion or a fault on the existing route rather than a reroute.
Cross-probe verdict. Only one probe saw it. We treat this as a probable false positive and label it as such.
Timeline
- Alert 2026051201: warning — ratio 2.71x
- Alert #116 improving: 1/3 consecutive OK
- Alert #116 resolved: RTT 76.58ms (baseline 42.24ms), 3 consecutive OK
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.
