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 151 ms over the last day vs 314 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 78 ms over 30 days |
Dependence is structural (share of the country's submarine cables), not a traffic share: real traffic distribution across cables is not public.

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.
