Costa Rica Experiences Brief Internet Connectivity Disruption

Costa Rica experienced a significant but brief internet connectivity disruption on June 20, 2026. The event lasted approximately one and a half hours, starting at 12:20 UTC and ending by 13:50 UTC. The primary impact was observed in network reachability metrics.

Technical Details

The disruption registered a severity score of 8,875. The most severely affected signal was the ping-slash24 metric, which measures ICMP reachability across IPv4 /24 prefixes. This signal recorded a drop magnitude of -99% from its peak, indicating a sharp decline in active network reachability.

Other signals showed varied impacts. The gtr.sarima signal, which tracks deviation from an expected traffic baseline, recorded a -60% drop. The merit-nt signal, a proxy for aggregate connectivity, showed a -51% drop. The bgp signal, which monitors control plane visibility for network prefixes, remained stable with no significant drop observed.

Reported Cause

The cause of the disruption has not been publicly attributed.

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