French Polynesia Connectivity Disruption Lasted Nearly Three Days

French Polynesia experienced a significant connectivity disruption lasting nearly three days, beginning on July 21 and ending on July 24. The event primarily affected the Border Gateway Protocol (BGP), which manages routing information between networks.

Technical Details

The disruption began at approximately 03:20 UTC on July 21 and persisted until 00:30 UTC on July 24. The BGP signal recorded a severity score of 5,046. This signal reflects the stability of routing announcements for network prefixes. The median number of visible BGP routes remained stable at 325 throughout the event.

Other network signals showed varied impacts. The gtr-norm signal, a measure of traffic volume relative to a baseline, dropped by approximately 18% from its peak. The merit-nt signal, which uses backscatter measurements as a proxy for aggregate connectivity, dropped to zero, indicating a complete loss of that measurement stream.

In contrast, the ping-slash24 signal, which measures ICMP reachability across IPv4 address blocks, showed only a minor 2% degradation, suggesting data-plane connectivity was largely maintained.

Reported Cause

The cause of the nearly three-day disruption has not been publicly attributed.

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