Bluesky Hit by Prolonged DDoS Attack, Causing Widespread Service Disruptions
Bluesky, the decentralized social media platform, has been battling a sustained distributed denial-of-service (DDoS) attack since April 15, leading to repeated outages and degraded service. The attack, which began around 8:40 p.m. Eastern Time, has overwhelmed the platform’s infrastructure with a flood of malicious traffic, disrupting core features such as timelines, notifications, threads, and search.
According to Bluesky COO Rose Wang, the attack is part of an ongoing cyber campaign targeting the platform. While DDoS attacks do not compromise internal systems or user data, they cripple service availability by overwhelming servers with bogus requests. Users have reported intermittent access issues, with error messages indicating rate limits and server strain.
Bluesky’s status page, currently unavailable, previously acknowledged the incident, stating that engineers were investigating disruptions in one of its regions. The company has pledged to provide updates on mitigation efforts by 1:00 p.m. Eastern Time on Friday. Despite the disruptions, Bluesky has assured users that their data remains secure.
The attack highlights the vulnerability of emerging platforms to large-scale cyber threats, with Bluesky’s team working to restore full functionality as the situation evolves.
