Azerbaijan registered a disruption to its internet control plane on Tuesday, affecting the visibility of its network prefixes. The event was observed between 22:25 and 00:30 UTC on July 8-9, lasting approximately two hours.

Technical Details

The disruption registered a severity score of 155. The primary affected metric was the BGP signal, which measures the control plane visibility of a country’s internet prefixes. The signal recorded a drop of approximately 1% from its peak, with the median number of visible prefixes falling from a high of 2,605 to a low of 2,573 during the event. Other traffic and reachability signals, including active probing and backscatter measurements, showed no significant correlated degradation.
