Bluesky blames app outage on ‘sophisticated’ DDoS attack

Bluesky said a sophisticated DDoS attack beginning April 15 caused widespread outages that disrupted feeds, notifications, threads and search, but engineers mitigated the attack and the application has remained stable since April 16. The company reported no evidence of unauthorized access to private user data while an Iran-linked group calling itself 313 Team claimed responsibility, though Bluesky has not confirmed the attribution. #Bluesky #313Team
