What we measured
| Cable | Kanawa |
| Segment | Schoelcher, MQ → Kourou, GF |
| Detected | 2026-08-21 00:02 UTC |
| Resolved | 2026-08-21 02:32 UTC |
| Duration | 2h 29m |
| Observed latency | 111.5 ms |
| Baseline | 326.3 ms · 2.09× |
| Increase | +109% |
| Severity | warning |
Who is affected
Countries where Kanawa comes ashore, how much of their submarine diversity this cable represents, and what our measurements into them show.
| Country | Dependence on this cable | Other submarine cables | What the measurements show |
|---|---|---|---|
| French Guiana resilience index: 40 · vulnerable |
1 of 3 cables (33% of submarine diversity) | Deep Blue One, EllaLink | average 154 ms over the last day vs 239 ms over 30 days - faster |
| Martinique resilience index: 48 · vulnerable |
1 of 5 cables (20% of submarine diversity) | ARIMAO, CELIA, Eastern Caribbean Fiber System (ECFS) +1 more | average 140 ms over the last day vs 149 ms over 30 days - unchanged |
Dependence is structural (share of the country's submarine cables), not a traffic share: real traffic distribution across cables is not public.
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. 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.
