Dominica Experienced Brief Connectivity Disruption Thursday

Dominica experienced a brief but significant degradation in internet connectivity on Thursday afternoon, local time. The disruption began at 16:00 UTC and lasted approximately 30 minutes, with a primary impact on network reachability.

Technical Details

The event recorded a severity score of 1,192. The most affected metric was the ping-slash24 signal, which measures ICMP reachability across the country’s IPv4 address space. This signal showed a 50% drop from its peak performance during the observation window.

Other signals showed varied impacts. The gtr-norm signal, which tracks normalized traffic volume, fell 68% from its peak. The merit-nt signal, a proxy for aggregate connectivity, dropped to zero. The Border Gateway Protocol (BGP) control plane, which manages routing announcements, remained stable with no observed change in the number of visible prefixes. The cause has not been publicly attributed.

Connectivity was reported restored by 16:30 UTC.
