Who is affected
Countries where Amitie 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 |
|---|---|---|---|
| France resilience index: 100 · resilient |
1 of 35 cables (3% of submarine diversity) | 2Africa, Africa Coast to Europe (ACE), Africa-1 +31 more | median 84 ms today vs 71 ms over 30 days (666 routes) - slower |
| United Kingdom resilience index: 100 · resilient |
1 of 68 cables (1% of submarine diversity) | 2Africa, Apollo, Atlantic Crossing-1 (AC-1) +64 more | median 64 ms today vs 73 ms over 30 days (1020 routes) - unchanged |
| United States resilience index: 100 · resilient |
1 of 122 cables (1% of submarine diversity) | ACS Alaska-Oregon Network (AKORN), AEC-1, Airraq +118 more | median 116 ms today vs 109 ms over 30 days (3311 routes) - 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. Other measurements did not confirm the event. We treat this as a probable false positive and label it as such.
Timeline
- Alert 2026101402: warning - ratio 2.69x
- Alert #228 improving: 1/3 consecutive OK
- Alert #228 resolved: RTT 90.06ms (baseline 105.45ms), 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.
