Nigeria Cameroon Submarine Cable System (NCSCS): 0.41× baseline latency

What we measured

Path analysis

Traffic changed route and the original path stopped responding. This is the pattern a real cable break produces.

Cross-probe verdict. Our own cross-check concluded this was an operator reroute, not a cable fault. We publish it anyway, labelled as such.

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.
