Who is affected
Countries where Apricot 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 |
|---|---|---|---|
| Guam resilience index: 83 · resilient |
1 of 18 cables (6% of submarine diversity) | Asia Connect Cable-1 (ACC-1), Atisa, Australia-Japan Cable (AJC) +14 more | median 299 ms today vs 305 ms over 30 days (24 routes) - unchanged |
| Indonesia resilience index: 100 · resilient |
1 of 73 cables (1% of submarine diversity) | Asia Connect Cable-1 (ACC-1), Asia United Gateway East (AUG East), Australia-Singapore Cable (ASC) +69 more | median 240 ms today vs 232 ms over 30 days (60 routes) - unchanged |
| Japan resilience index: 100 · resilient |
1 of 52 cables (2% of submarine diversity) | 5 Villages 6 Islands, APCN-2, Asia Direct Cable (ADC) +48 more | median 186 ms today vs 250 ms over 30 days (70 routes) - faster |
| Philippines resilience index: 100 · resilient |
1 of 25 cables (4% of submarine diversity) | APCN-2, Asia Connect Cable-1 (ACC-1), Asia Direct Cable (ADC) +21 more | median 275 ms today vs 273 ms over 30 days (24 routes) - unchanged |
| Singapore resilience index: 78 · resilient |
1 of 46 cables (2% of submarine diversity) | APCN-2, Asia Connect Cable-1 (ACC-1), Asia Direct Cable (ADC) +42 more | median 107 ms today vs 188 ms over 30 days (81 routes) - faster |
| Taiwan resilience index: 100 · resilient |
1 of 21 cables (5% of submarine diversity) | APCN-2, Asia Pacific Gateway (APG), Asia United Gateway East (AUG East) +17 more | no measurement today; median 327 ms over 30 days (1 routes) |
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. The effect was confined to a narrow set of paths, so a cable-wide fault is unlikely.
Timeline
- Alert #17: warning - Minamiboso
- Alert #17 resolved: Minamiboso
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.
