Dominica Connectivity Degradation Lasted Over One Hour
Dominica experienced a significant degradation in internet connectivity beginning late on June 18, 2026, lasting for over an hour. The disruption primarily affected the reachability of network prefixes across the country.
Technical Details
The event occurred between 23:20 UTC on June 18 and 00:30 UTC on June 19. The primary affected metric was the ping-slash24 signal, which measures ICMP reachability across IPv4 /24 prefixes. This signal recorded a severity score of 3,169, indicating a substantial drop in reachable networks.
Other network signals also showed deviations. The Border Gateway Protocol (BGP) signal, which reflects control plane visibility for network prefixes, saw a minor 4% drop from its peak. The gtr.sarima signal, a forecast model of expected traffic, deviated from its baseline, while the ucsd-nt signal, a proxy for aggregate connectivity based on backscatter, showed a complete drop to zero.
The cause has not been publicly attributed.
Connectivity was reported restored by the end of the observation window.
