Timor-Leste experiences brief internet routing disruption

Timor-Leste experienced a brief but significant internet connectivity disruption early Friday, August 7, affecting the country’s routing infrastructure. The event began at 01:55 UTC and concluded by 02:35 UTC, lasting approximately 40 minutes.

Technical Details

The primary signal affected was the Border Gateway Protocol (BGP), which governs how internet traffic is routed between networks. The BGP median signal recorded a severity score of 139 during the event, with a measured drop of 3% from its peak stability. This indicates a reduction in the number of visible network paths.

Concurrently, a key traffic forecast model, gtr.sarima, showed a deviation from its expected baseline. The normalized traffic signal, gtr.norm, recorded a more pronounced drop of 67% from its peak. Active probing for ICMP reachability across IPv4 /24 prefixes, measured by the ping-slash24 signal, also showed a reduction, with a 9% drop from its peak.

The cause has not been publicly attributed. Connectivity was reported restored following the 40-minute disruption.
