Dominica Experienced Connectivity Disruption Lasting 3.5 Hours
Dominica experienced a significant degradation in internet connectivity on Wednesday, June 4, 2026. The disruption began at 15:50 UTC and lasted for approximately 3.5 hours, ending at 19:20 UTC. The event was characterized by a sharp decline in network reachability across the country.
Technical Details
The primary affected metric was the ping-slash24 signal, which measures ICMP reachability across IPv4 /24 network prefixes. This signal recorded a severity score of 7,255, with a measured drop in reachability of 38% from its peak. During the event, the average number of reachable prefixes fell to 51 from a typical range.
Other network signals showed concurrent anomalies. The BGP control plane signal, which reflects routing visibility for network prefixes, showed a minor 4% deviation. The gtr-norm signal, a forecast deviation from an expected traffic baseline, recorded a 37% drop from its peak. The merit-nt signal, a backscatter measurement used as a proxy for aggregate connectivity, fell to zero during the disruption.
Reported Cause
The cause of the disruption has not been publicly attributed.
Connectivity was reported restored by the end of the observation period.
