Who is affected
Countries where Colombia-Florida Express (CFX-1) 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 |
|---|---|---|---|
| Colombia resilience index: 100 · resilient |
1 of 12 cables (8% of submarine diversity) | America Movil Submarine Cable System-1 (AMX-1), ARCOS, Carnival Submarine Network-1 (CSN-1) +8 more | no measurement today; median 64 ms over 30 days (33 routes) |
| Jamaica resilience index: 73 · moderate |
1 of 7 cables (14% of submarine diversity) | ALBA-1, Cayman-Jamaica Fiber System (CJFS), East-West Cable (EWC) +3 more | average 90 ms over the last day vs 63 ms over 30 days - slower |
| United States resilience index: 100 · resilient |
1 of 122 cables (1% of submarine diversity) | ACS Alaska-Oregon Network (AKORN), AEC-1, Airraq +118 more | median 116 ms today vs 108 ms over 30 days (3282 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.

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.
