DDoS Attacks Expose Scale Challenges for Twitter Alternatives Mastodon and Bluesky

Mastodon and Bluesky, the main Twitter replacements, faced coordinated attacks that disrupted feeds, notifications, and search this week. Both confirmed no data was stolen. Analysis: The parallel targeting reveals why decentralized platforms struggle as they grow beyond early adopters. Mastodon's federated design—where thousands of independent servers connect—creates more attack points. Bluesky's more centralized setup lacks defensive systems that established platforms built over decades. The coordinated nature suggests adversaries are testing decentralized platform defenses rather than pursuing specific grievances.
