Liberia experiences brief internet connectivity degradation

Liberia experienced a brief but significant degradation in internet connectivity early Friday, June 27. The disruption lasted approximately one hour, beginning at 04:20 UTC and ending at 05:20 UTC. The primary impact was observed in the reachability of the country’s core internet address blocks.

Technical Details

The event registered a severity score of 1,500. The most affected signal measured ICMP reachability across Liberia’s IPv4 /24 network prefixes, which showed a 25% drop from its peak. Active probing across these prefixes confirmed reduced reachability during the disruption window.

Other measurement signals showed mixed results. The Border Gateway Protocol (BGP) control plane, which governs routing announcements, remained stable with no observed drop. Backscatter measurements, a proxy for aggregate network activity, showed a complete 100% drop from peak. A separate traffic forecast model also indicated a deviation from the expected baseline.

The cause has not been publicly attributed.

Connectivity was reported restored by 05:20 UTC.
