Kazakhstan experienced a brief but notable disruption to its internet control plane on August 3, 2026. The event, which lasted approximately 75 minutes, was characterized by a significant drop in Border Gateway Protocol (BGP) visibility. The disruption began at 19:15 UTC and concluded by 20:30 UTC.
Technical Details
The event registered a severity score of 78, primarily driven by a degradation in the BGP signal. The BGP.median measurement, which tracks the control plane visibility of network prefixes, recorded a drop in its normalized value from a peak of 0.99 to a low of 0.31, a 69% decline. This indicates a reduction in the number of network routes being advertised and seen globally.
Other network signals showed less pronounced effects. The ping-slash24 metric, which measures ICMP reachability across IPv4 address blocks, saw only a 1% dip in active prefixes. Backscatter traffic measurements from the Merit Network Telescope also indicated a 46% drop from its peak during the observation window.
Reported Cause
The cause of the disruption has not been publicly attributed.
Network connectivity was reported as restored by the end of the observation period.
