Singapore experienced a brief but measurable degradation in internet connectivity early on August 23. The disruption, which affected IPv4 network reachability, lasted approximately 40 minutes, beginning at 01:10 UTC.
Technical Details
The primary affected metric was the ping-slash24 signal, which measures ICMP reachability across IPv4 /24 network prefixes. The signal recorded a severity score of 894, with a measured drop of 33% from its peak value during the observation window. Other monitored signals, including Border Gateway Protocol (BGP) control plane visibility and backscatter traffic measurements, showed minimal deviation from normal baselines.
The cause has not been publicly attributed. Connectivity was reported restored by 01:50 UTC.
