Iraq Connectivity Degradation Observed Early June 21
Iraq experienced a degradation in internet connectivity between 03:00 and 04:30 UTC on June 21. The disruption lasted approximately 1.5 hours and was characterized by a significant drop in network reachability.
Technical Details
The event registered a severity score of 5,941. The primary affected metric was the ping-slash24 signal, which measures ICMP reachability across IPv4 /24 prefixes. This signal showed a drop of 69% from its peak observed value during the observation window.
Other network signals also showed deviations. The Border Gateway Protocol (BGP) signal, which reflects control plane visibility for prefixes, recorded a 18% drop. The gtr.sarima signal, a forecast deviation from expected traffic baseline, dropped by 52%. The merit-nt signal, a backscatter measurement used as a proxy for aggregate connectivity, fell by 78%.
The cause has not been publicly attributed.
The disruption concluded by 04:30 UTC.
