Quien esta afectado
Paises donde Australia-Singapore Cable (ASC) llega a tierra, que parte de su diversidad submarina representa este cable y que miden ahora nuestras sondas hacia ellos.
| Pais | Dependencia de este cable | Otros cables submarinos | Nuestras sondas ven |
|---|---|---|---|
| Australia indice de resiliencia: 100 · resiliente |
1 de 34 cables (3% de la diversidad submarina) | APX East, Asia Connect Cable-1 (ACC-1), Australia-Japan Cable (AJC) +30 mas | mediana 333 ms hoy frente a 317 ms en 30 dias (6 rutas) - sin cambios |
| Isla de Navidad indice de resiliencia: 41 · vulnerable |
1 de 4 cables (25% de la diversidad submarina) | Bosun, Dhivaru, TalayLink | no medimos rutas hacia este pais |
| Indonesia indice de resiliencia: 100 · resiliente |
1 de 73 cables (1% de la diversidad submarina) | Apricot, Asia Connect Cable-1 (ACC-1), Asia United Gateway East (AUG East) +69 mas | mediana 258 ms hoy frente a 251 ms en 30 dias (6 rutas) - sin cambios |
| Singapur indice de resiliencia: 78 · resiliente |
1 de 46 cables (2% de la diversidad submarina) | APCN-2, Apricot, Asia Connect Cable-1 (ACC-1) +42 mas | mediana 219 ms hoy frente a 222 ms en 30 dias (6 rutas) - sin cambios |
La dependencia es estructural (parte de este cable entre los cables submarinos del pais), no una cuota de trafico. Los enlaces terrestres no se miden.

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.
