Hong Kong experienced a brief but sharp connectivity disruption on Wednesday, July 30, 2026. The event was observed between 15:05 and 15:12 UTC, lasting approximately seven minutes. A severity score of 530 was recorded, primarily associated with a single, significant drop in a key network traffic signal.
Technical Details
The disruption was characterized by a 53% drop in the median value of the merit-nt signal, which serves as a proxy for aggregate connectivity based on backscatter measurements. This sharp decline was the primary contributor to the event’s severity score. Other network health indicators showed minimal deviation; the Border Gateway Protocol (BGP) control plane remained stable, and active probing for IPv4 reachability (ping-slash24) showed only a 1% reduction from its peak.
The cause of the brief disruption has not been publicly attributed. Connectivity was reported restored following the seven-minute event window.
