Who is affected
Countries where Sorsogon-Samar Submarine Fiber Optical Interconnection Project (SSSFOIP) 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 |
|---|---|---|---|
| Philippines resilience index: 100 · resilient |
1 of 26 cables (4% of submarine diversity) | APCN-2, Apricot, Asia Connect Cable-1 (ACC-1) +22 more | median 196 ms today vs 243 ms over 30 days (102 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
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. Our own cross-check concluded this was an operator reroute, not a cable fault. We publish it anyway, labelled as such.

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.
