Bluesky, Fast-Growing X Alternative, Hit by Sophisticated DDoS Attack

A sophisticated DDoS campaign targeted Bluesky beginning the night of April 15, 2026, causing widespread interruptions to core functions (feeds, notifications, threads, search). Engineers worked overnight and the platform stabilized by the evening of April 16; Bluesky reported no evidence of unauthorized access to user data. A group identifying as "313 Team" claimed responsibility, but the company has not attributed the attack to a specific actor. The incident coincides with rapid user growth for the platform (~43.7 million users).
