Who is affected
Countries where TE North/TGN-Eurasia/SEACOM/Alexandros/Medex 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 |
|---|---|---|---|
| Algeria resilience index: 88 · resilient |
1 of 7 cables (14% of submarine diversity) | Africa-1, Alpal-2, Med Cable Network +3 more | average 56 ms over the last day vs 71 ms over 30 days - faster |
| Cyprus resilience index: 88 · resilient |
1 of 14 cables (7% of submarine diversity) | Blue, CADMOS, CADMOS-2 +10 more | average 87 ms over the last day vs 97 ms over 30 days - unchanged |
| Egypt resilience index: 100 · resilient |
1 of 24 cables (4% of submarine diversity) | 2Africa, Africa-1, Aletar +20 more | no measurement today; median 141 ms over 30 days (6 routes) |
| France resilience index: 97 · resilient |
1 of 34 cables (3% of submarine diversity) | 2Africa, Africa Coast to Europe (ACE), Africa-1 +30 more | median 67 ms today vs 69 ms over 30 days (88 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
No usable traceroute data for this window.
Cross-probe verdict. The effect was confined to a narrow set of paths, so a cable-wide fault is unlikely.
Timeline
- Alert #39: warning - Marseille
- Alert #39 resolved: Marseille
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.
