A DDoS attack is a form of cyber warfare where attackers use a network of compromised computers to bombard a target's infrastructure with traffic, rendering its servers inaccessible to legitimate users. For Bluesky, this has caused intermittent outages and performance issues.

The sustained DDoS attack has caused major outages and performance degradation for nearly a full day. Bluesky's engineering team is continuously implementing mitigation efforts to stabilize the service.

While Bluesky is a decentralized social media platform built on the AT Protocol, its core application services still rely on centralized servers. These servers can become bottlenecks and targets for malicious floods of traffic, as seen with this DDoS attack.

A prolonged major outage can stifle Bluesky's momentum and raise questions about its technical resilience and ability to maintain user trust against competitors like X (formerly Twitter) and Meta's Threads. Reliability and uptime are crucial differentiators in the social media market.

Bluesky's engineering and security teams are actively working on mitigating the ongoing Distributed Denial-of-Service (DDoS) attack. They are implementing continuous countermeasures to combat the malicious flood of traffic and stabilize the service for their user base.
