Bluesky suffers second DDoS attack in four months, pro-Iran group claims credit

Bluesky confirmed a day-long DDoS disruption on August 18, 2026. A pro-Iran group claimed responsibility on the IFIN forum. DDoS attacks flood a service with traffic until it buckles. It is the platform's second such event since April. Bluesky said it "upgraded our defenses" but disclosed no specific mitigation partners or strategies.
