Canonical hit by sustained DDoS attack as Ubuntu 26 releases; Iranian group 313 Team claims responsibility

Canonical said a sustained DDoS attack disrupted Ubuntu-related websites and services, including mirrors, Launchpad, the Snap Store, and SSO.

The attack reportedly claimed by 313 Team caused slowdowns and outages, but Canonical said there is no sign of repository or ISO compromise.

The disruption comes as Ubuntu 26 LTS is being widely adopted, raising concern about downloads, updates, and account access.
