BLUESKY suffered a 24-hour DDoS attack that disrupted its services for about a day, beginning on 15 April 2026. Bluesky is described as a decentralised, open‑source microblogging platform similar to X (formerly Twitter), allowing users to post short messages with more control over algorithms, data and moderation. The attack affected feeds, notifications, threads and search, causing intermittent outages, though Bluesky stated there was no evidence of data breaches.
A pro‑Iran hacker group, 313 Team, claimed responsibility for the disruption. The company indicated the incident was mitigated through the night and that they limited the impact to avoid prolonged outages, with no signs of unauthorised access to private user data, according to the article.
