Who is affected
Countries where SEAX-1 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 |
| Singapore resilience index: 78 · resilient |
1 of 46 cables (2% of submarine diversity) | APCN-2, Apricot, Asia Connect Cable-1 (ACC-1) +42 more | median 107 ms today vs 188 ms over 30 days (81 routes) - faster |
Dependence is structural (share of the country's submarine cables), not a traffic share: real traffic distribution across cables is not public.
Path analysis
No usable traceroute data for this window.
Cross-probe verdict. Too few independent vantage points were watching this endpoint to reach a cross-probe verdict.
Timeline
- Alert #30: warning - Batam
- Alert #30 resolved: Batam
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.
