East-West Submarine Cable System: 0.85× baseline latency

What we measured

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

Timeline

• 2026-06-12 09:01 UTC Alert 2026061201: warning — ratio 2.69x
• 2026-06-12 10:00 UTC Alert #134 improving: 1/3 consecutive OK
• 2026-06-12 10:31 UTC Alert #134 resolved: RTT 15.8ms (baseline 18.49ms), 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.
