## Executive Summary Since June 18, 2025 Iran experienced a near-complete internet blackout as observed by Censys; the report documents dramatic drops in observable hosts across many autonomous systems, divergent recovery patterns through June 23, and identifies AS49666 (Telecommunication Infrastructure Company) as a common transit provider likely central to the disruption. The analysis enumerates ASNs with the weakest and strongest recoveries, presents host-count trends and dashboards, and notes possible government involvement via TIC while avoiding conclusive attribution.
