Nauru Experienced Brief BGP Disruption on July 9

Nauru experienced a brief but notable connectivity disruption on July 9, 2026, centered on its internet routing infrastructure. The event began at 04:15 UTC and lasted for approximately 15 minutes, with a severity score of 43 attributed to a drop in BGP visibility.

Technical Details

The disruption was characterized by a degradation in the Border Gateway Protocol (BGP) signal, which reflects the control plane visibility of a country’s internet prefixes. The BGP median signal dropped by 9% from its peak during the event. Concurrently, other network health indicators showed declines: the ping-slash24 signal, which measures ICMP reachability across IPv4 address blocks, fell by 29%, and a normalized traffic volume metric dropped by 35%. The cause has not been publicly attributed.

Network conditions were observed to have returned to baseline levels following the brief event.
