BCS North - Phase 2: 1.27× baseline latency

What we measured

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. Some probes saw the degradation and others did not, which usually means a partial or regional effect.

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.
