Timor-Leste experienced a brief but notable internet connectivity disruption on Monday, July 21, 2026. The event was characterized by instability in the network’s control plane and lasted for approximately 40 minutes. The disruption was first observed at 09:55 UTC, with connectivity reported restored by 10:35 UTC.

Technical Details

The event recorded a severity score of 70. The primary affected signal was the Border Gateway Protocol (BGP) median, which measures the control plane visibility of network prefixes. The BGP signal showed a 2% drop from its peak stability during the observation window. Concurrently, the ping-slash24 signal, which measures ICMP reachability across IPv4 /24 prefixes, showed a 12% reduction in reachability. The gtr-norm signal, a forecast deviation from expected traffic baselines, recorded a more significant 72% drop from its peak.

The cause has not been publicly attributed.

Network conditions were reported as stable following the 10:35 UTC restoration.
