Hong Kong experienced a brief but sharp degradation in internet connectivity early on August 3, 2026. The disruption occurred between 01:09 and 01:17 UTC, lasting approximately eight minutes. The primary impact was observed on a key network traffic metric.
Technical Details
The disruption recorded a severity score of 619. The Merit Network Telescope (merit-nt) signal, which measures backscatter traffic as a proxy for aggregate connectivity, showed an 80% drop from its peak value during the event. The signal’s median value fell to 91.8 from a typical average of 359.36.
Other core internet signals showed minimal deviation. Border Gateway Protocol (BGP) announcements, which reflect routing control plane stability, remained consistent. Active probing for IPv4 reachability (ping-slash24) also showed only a 1% decline, indicating the event’s primary impact was on data plane traffic rather than network availability.
The cause has not been publicly attributed.
Connectivity was reported restored shortly after the disruption began.
