Who is affected
Countries where Malaysia-Cambodia-Thailand (MCT) Cable 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 |
|---|---|---|---|
| Cambodia resilience index: 37 · vulnerable |
1 of 3 cables (33% of submarine diversity) | Asia Africa Europe-1 (AAE-1), Sihanoukville-Hong Kong (SHV-HK) | average 236 ms over the last day vs 44 ms over 30 days - slower |
| Malaysia resilience index: 100 · resilient |
1 of 33 cables (3% of submarine diversity) | APCN-2, Asia Africa Europe-1 (AAE-1), Asia Link Cable (ALC) +29 more | median 218 ms today vs 235 ms over 30 days (6 routes) - unchanged |
| Thailand resilience index: 100 · resilient |
1 of 18 cables (6% of submarine diversity) | Asia Africa Europe-1 (AAE-1), Asia Direct Cable (ADC), Asia Pacific Gateway (APG) +14 more | median 225 ms today vs 228 ms over 30 days (15 routes) - unchanged |
Dependence is structural (share of the country's submarine cables), not a traffic share: real traffic distribution across cables is not public.

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.
