Chile Experiences Brief BGP Control Plane Disruption

Chile experienced a brief but notable disruption to its internet control plane on Monday, August 10, 2026. The event, centered on Border Gateway Protocol (BGP) activity, lasted approximately one hour and twenty-five minutes, beginning at 17:30 UTC.

Technical Details

The disruption was isolated to the BGP control plane, which governs the routing of traffic between networks. The bgp.median signal, a measure of visible routing prefixes, recorded a severity score of 140 during the event. The signal showed a 2% drop from its peak value, with the number of visible prefixes falling from a high of 37,110 to a low of 36,500.

Other key internet health indicators, including active probing for IPv4 reachability (ping-slash24) and traffic volume measurements (gtr), remained stable and showed no significant concurrent degradation. This pattern suggests the event was primarily a routing visibility issue rather than a widespread loss of data plane connectivity.

The cause has not been publicly attributed.

Network conditions were reported as stable following the event’s conclusion at 18:55 UTC.
