Who is affected
Countries where Gemini Bermuda 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), GlobeNet +2 more | median 164 ms today vs 172 ms over 30 days (7 routes) - unchanged |
| 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
Not enough history on this endpoint to compare the path against a baseline.
Cross-probe verdict. Too few independent vantage points were watching this endpoint to reach a cross-probe verdict.
Timeline
- Alert #45: warning (backfilled)
- Alert #45 improving: 1/3 consecutive OK checks
- Alert #45 improving: 2/3 consecutive OK checks
- Alert #45 resolved: RTT 61.41ms (baseline 69.69ms)
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.
