Who is affected
Countries where Batam Sarawak Internet Cable System (BaSICS) 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 |
|---|---|---|---|
| Indonesia resilience index: 100 · resilient |
1 of 73 cables (1% of submarine diversity) | Apricot, Asia Connect Cable-1 (ACC-1), Asia United Gateway East (AUG East) +69 more | median 240 ms today vs 232 ms over 30 days (60 routes) - unchanged |
| Malaysia resilience index: 100 · resilient |
1 of 33 cables (3% of submarine diversity) | APCN-2, Asia Africa Europe-1 (AAE-1), Asia Link Cable (ALC) +29 more | median 218 ms today vs 235 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.
