Who is affected
Countries where GlobeNet 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 |
|---|---|---|---|
| Bermuda resilience index: 52 · vulnerable |
1 of 6 cables (17% of submarine diversity) | Canoa, Caribbean-Bermuda U.S. (CBUS), Gemini Bermuda +2 more | median 164 ms today vs 172 ms over 30 days (7 routes) - unchanged |
| Brazil resilience index: 100 · resilient |
1 of 26 cables (4% of submarine diversity) | America Movil Submarine Cable System-1 (AMX-1), Brazilian Festoon, BRUSA +22 more | median 144 ms today vs 152 ms over 30 days (378 routes) - unchanged |
| 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) |
| 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 |
| Venezuela resilience index: 84 · resilient |
1 of 6 cables (17% of submarine diversity) | ALBA-1, ARCOS, Fénix +2 more | average 131 ms over the last day vs 134 ms over 30 days - 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. Too few independent vantage points were watching this endpoint to reach a cross-probe verdict.
Timeline
- Alert #6: warning - Southport
- Alert #6 resolved: Southport
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.
