Who is affected
Countries where Indonesia Global Gateway (IGG) System 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 243 ms today vs 202 ms over 30 days (1061 routes) - slower |
| 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 202 ms today vs 163 ms over 30 days (509 routes) - slower |
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. Too few independent vantage points were watching this endpoint to reach a cross-probe verdict.

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.
