Mastodon Recovers After Major DDoS Attack
21 Apr
Summary
- Mastodon's main server was inaccessible due to a DDoS attack.
- The platform implemented countermeasures to restore service.
- Bluesky also recently experienced a significant DDoS incident.

The decentralized social media platform Mastodon is recovering after a significant Distributed Denial of Service (DDoS) attack. The primary mastodon.social instance experienced widespread inaccessibility starting early Monday. Mastodon's head of communications characterized the event as "major."
Countermeasures were implemented, and access to mastodon.social has been largely restored. However, ongoing instability remains a possibility as the service fully stabilizes. It is unclear if other Mastodon instances were targeted.
This incident mirrors a recent DDoS attack on Bluesky, another decentralized platform. Bluesky reported its service had stabilized following the attack last week, with no evidence of private data compromise. However, Bluesky later experienced renewed issues, including elevated errors on some hosted services.
