Who is affected
Countries where Sweden-Estonia (EE-S 1) 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 |
|---|---|---|---|
| Estonia resilience index: 80 · resilient |
1 of 8 cables (13% of submarine diversity) | Baltic Sea Submarine Cable, E-FINEST, Finland Estonia Connection 1 (FEC-1) +4 more | median 66 ms today vs 65 ms over 30 days (6 routes) - unchanged |
| Sweden resilience index: 100 · resilient |
1 of 29 cables (3% of submarine diversity) | Baltic Sea Submarine Cable, Baltica, BCS East-West Interlink +25 more | median 68 ms today vs 71 ms over 30 days (42 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.
