Who is affected
Countries where Maldives Sri Lanka Cable (MSC) 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 |
|---|---|---|---|
| Maldives resilience index: 100 · resilient |
1 of 11 cables (9% of submarine diversity) | Dhiraagu Cable Network, Dhiraagu-SLT Submarine Cable Network, Dhivaru +7 more | average 191 ms over the last day vs 126 ms over 30 days - slower |
| Sri Lanka resilience index: 76 · resilient |
1 of 9 cables (11% of submarine diversity) | Bay of Bengal Gateway (BBG), Bharat Lanka Cable System, Dhiraagu-SLT Submarine Cable Network +5 more | median 229 ms today vs 205 ms over 30 days (40 routes) - unchanged |
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 changed route while latency was elevated. A reroute of this kind usually follows a fault somewhere on the original path.
Cross-probe verdict. Our own cross-check concluded this was an operator reroute, not a cable fault. We publish it anyway, labelled as such.
Timeline
- Alert 2026102201: warning - ratio 2.21x
- Alert #237 improving: 1/3 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.
