Who is affected
Countries where Italy-Libya 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 |
|---|---|---|---|
| Italy resilience index: 97 · resilient |
1 of 38 cables (3% of submarine diversity) | 2Africa, ANDROMEDA, Asia Africa Europe-1 (AAE-1) +34 more | median 68 ms today vs 72 ms over 30 days (19 routes) - unchanged |
| Libya resilience index: 84 · resilient |
1 of 6 cables (17% of submarine diversity) | Europe India Gateway (EIG), LFON (Libyan Fiber Optic Network), Medusa Submarine Cable System +2 more | median 182 ms today vs 181 ms over 30 days (6 routes) - unchanged |
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.
