Who is affected
Countries where Tata TGN-Gulf 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 |
|---|---|---|---|
| Bahrain resilience index: 62 · moderate |
1 of 7 cables (14% of submarine diversity) | 2Africa, FALCON, Fiber Optic Gulf (FOG) +3 more | median 72 ms today vs 67 ms over 30 days (5 routes) - unchanged |
| Oman resilience index: 100 · resilient |
1 of 20 cables (5% of submarine diversity) | 2Africa, Asia Africa Europe-1 (AAE-1), Bay of Bengal Gateway (BBG) +16 more | median 144 ms today vs 182 ms over 30 days (10 routes) - faster |
| Qatar resilience index: 83 · resilient |
1 of 9 cables (11% of submarine diversity) | 2Africa, Asia Africa Europe-1 (AAE-1), FALCON +5 more | median 169 ms today vs 185 ms over 30 days (6 routes) - unchanged |
| Saudi Arabia resilience index: 100 · resilient |
1 of 25 cables (4% of submarine diversity) | 2Africa, Africa-1, Asia Africa Europe-1 (AAE-1) +21 more | median 155 ms today vs 148 ms over 30 days (15 routes) - unchanged |
| United Arab Emirates resilience index: 100 · resilient |
1 of 22 cables (5% of submarine diversity) | 2Africa, Africa-1, Asia Africa Europe-1 (AAE-1) +18 more | median 102 ms today vs 161 ms over 30 days (25 routes) - faster |
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.
