Who is affected
Countries where Batam Dumai Melaka (BDM) 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.
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. Only one probe saw it. We treat this as a probable false positive and label it as such.
Timeline
- Alert 2026041302: warning - ratio 2.86x
- Alert #71 improving: 1/3 consecutive OK
- Alert #71 resolved: RTT 17.72ms (baseline 30.54ms), 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.
