Bosnia and Herzegovina Registers BGP Control Plane Disruption

Bosnia and Herzegovina experienced a disruption to its internet routing control plane on Monday morning, July 21, 2026. The event, which lasted approximately 50 minutes, was characterized by a degradation in the Border Gateway Protocol (BGP) signal.

Technical Details

The disruption occurred between 04:50 and 05:40 UTC. A severity score of 80 was recorded for the event, based on the BGP.median signal. This signal measures the visibility of network prefixes in the global routing control plane. The BGP prefix count dropped by 3% from its peak during the observation window from 02:30 to 08:30 UTC.

Other internet measurement signals showed less pronounced deviations. The ping-slash24 signal, which measures ICMP reachability across IPv4 network blocks, recorded a 6% drop from its peak. The gtr-norm signal, a normalized traffic volume indicator, saw a 66% decline from its observed peak.

Reported Cause

The cause of the routing disruption has not been publicly attributed.

Network routing was reported restored by 05:40 UTC.
