| Segment | Sydney, AU → Sungailiat, ID |
| Detected | 2026-09-05 04:32 UTC |
| Resolved | 2026-09-06 00:01 UTC |
| Duration | 19h 29m |

| Severity | warning |
Who is affected
Countries where Link 5 Phase-2 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 |
Dependence is structural (share of the country's submarine cables), not a traffic share: real traffic distribution across cables is not public.
Timeline
- Alert 2026090504: warning - ratio 2.04x
- Alert #190 resolved: RTT 188.68ms (baseline 128.95ms), 6 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.
