Who is affected
Countries where Apricot comes ashore, how much of their submarine diversity this cable represents, and what our measurements into them show.

| 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 155 ms today vs 163 ms over 30 days (509 routes) - unchanged |
| 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 | median 9 ms today vs 147 ms over 30 days (129 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. The effect was confined to a narrow set of paths, so a cable-wide fault is unlikely.

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.
