Quién está afectado
Países donde Fibralink llega a tierra, qué parte de su diversidad submarina representa este cable y qué muestran nuestras mediciones hacia ellos.
| País | Dependencia de este cable | Otros cables submarinos | Qué muestran las mediciones |
|---|---|---|---|
| República Dominicana índice de resiliencia: 90 · resiliente |
1 de 10 cables (10% de la diversidad submarina) | Alisios, America Movil Submarine Cable System-1 (AMX-1), Antillas 1 +6 más | media 241 ms en 24 h frente a 160 ms en 30 días - más lento |
| Haití índice de resiliencia: 43 · enlaces terrestres |
1 de 2 cables (50% de la diversidad submarina) | Bahamas Domestic Submarine Network (BDSNi) | media 31 ms en 24 h frente a 43 ms en 30 días - más rápido |
| Jamaica índice de resiliencia: 73 · medio |
1 de 7 cables (14% de la diversidad submarina) | ALBA-1, Cayman-Jamaica Fiber System (CJFS), Colombia-Florida Express (CFX-1) +3 más | media 109 ms en 24 h frente a 81 ms en 30 días - más lento |
La dependencia es estructural (parte de este cable entre los cables submarinos del país), no una cuota de tráfico: el reparto real del tráfico entre cables no es público.
Path analysis
Not enough history on this endpoint to compare the path against a baseline.
Cross-probe verdict. Too few independent vantage points were watching this endpoint to reach a cross-probe verdict.
Timeline
- Alert 2026041001: warning - ratio 2.31x
- FALSE POSITIVE [T12]: target_ip switched from 196.1.64.1 (CWC Jamaica, verified, ~21.5ms) to 74.222.64.16 (Cayman Islands probe #1003574, approximate, ~47ms) during landing_point_targets populate on 2026-04-10 12:24. Baseline computed from pre-switch verified rows; current measured to physically different cross-border endpoint. Not a cable degradation. See SESSION_2026-04-10d_T12 brief.
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.
