Syria experiences multi-day BGP connectivity disruption

Syria experienced a significant disruption to its internet control plane visibility beginning on July 26. The event, which lasted for approximately 1.7 days, was characterized by a pronounced degradation in Border Gateway Protocol (BGP) activity, a key signal for routing stability.

Technical Details

The disruption period was observed from 08:10 UTC on July 26 to 00:30 UTC on July 28. The primary affected metric was the BGP median signal, which registered a severity score of 4,370. The BGP signal measures the control plane visibility of network prefixes, indicating the stability of routing announcements and withdrawals. While other metrics, including active probing reachability and backscatter measurements, showed less severe fluctuations, the BGP degradation was the most pronounced technical signature of the event.

The cause has not been publicly attributed.

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