MASTODON was hit by a major DDoS attack just days after a similar disruption affected Bluesky, with the outage on Mastodon described as significant but resolved within a few hours. The incident timeline shows the issues beginning on 20 April 2026, when the platform reported it was experiencing a DDoS attack and later stated countermeasures had been implemented and the site was accessible again.
Bluesky had previously endured a 24-hour DDoS attack claimed by a pro-Iran group, underscoring a continuing wave of disruptions across decentralised and centralised social networks. The Mastodon attack was quickly mitigated by its team, restoring normal service within hours, while Bluesky’s incident remains attributed to an unnamed pro-Iran actor in the linked report. A group called 313 Team claimed responsibility for the Bluesky disruption, though no threat actor has publicly taken credit for the Mastodon assault.
