Syria experienced a significant disruption to its internet routing infrastructure on Saturday, July 26, affecting the Border Gateway Protocol (BGP) control plane for over four hours. The event began at 08:10 UTC and concluded at approximately 12:30 UTC, with a severity score of 470 recorded for the affected signal.
Technical Details
The disruption primarily impacted the BGP signal, which measures the visibility of network prefixes in the global routing table. The median BGP signal dropped by 2% from its peak, with a recorded low of 4,786 visible prefixes. The event lasted for 4.3 hours. Other connectivity metrics, including active probing for IPv4 reachability and backscatter measurements, showed minimal deviation during the same observation window.
The cause has not been publicly attributed.
Connectivity was reported restored by the end of the observation period.
