Dominica Experiences Connectivity Disruption Lasting Nearly Four Hours

Dominica experienced a significant degradation in internet connectivity on Wednesday, June 17, 2026. The disruption began at 08:40 UTC and persisted for approximately 3.8 hours, with a final observation of restoration at 12:30 UTC. The event primarily impacted the reachability of the country’s IP address space.

Technical Details

The disruption registered a severity score of 5,275. The primary affected metric was the ping-slash24 signal, which measures ICMP reachability across the nation’s IPv4 address prefixes. This signal recorded a 42% drop from its normal peak levels, indicating widespread packet loss for active probes. Other network telemetry signals, including Border Gateway Protocol (BGP) control plane visibility and backscatter measurements, did not show significant deviations during the event window.

The cause has not been publicly attributed. No official statements or reports from local authorities or service providers were identified in the immediate aftermath of the disruption.

Connectivity was reported restored by the end of the observation period.
