Sri Lanka experiences brief connectivity disruption

Sri Lanka experienced a brief but significant degradation in internet connectivity on June 20, 2026. The disruption lasted approximately 90 minutes, beginning at 12:20 UTC and concluding by 13:50 UTC. The event was characterized by a sharp drop in network reachability.

Technical Details

The disruption registered a severity score of 8,875. The primary affected metric was the ping-slash24 signal, which measures ICMP reachability across IPv4 /24 network prefixes. The signal showed a drop magnitude of 99% from its peak, indicating widespread packet loss.

Other network signals showed varied behavior. The Border Gateway Protocol (BGP) control plane, which governs routing announcements, remained stable with no observed drop. The gtr-norm signal, which tracks deviation from a forecasted traffic baseline, recorded a 10% drop. The merit-nt signal, a proxy for aggregate connectivity, showed an 82% drop from its peak.

The cause has not been publicly attributed.

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