Canonical, the company behind Ubuntu, confirmed that its infrastructure has been under a distributed denial‑of‑service attack for more than 15 hours. The outage surfaced on the status page early this morning, prompting users of Ubuntu Cloud, Launchpad and the Snap Store to experience intermittent connectivity. Engineers are actively filtering malicious traffic while keeping core services online. Traffic spikes have been measured across all edge nodes.

A DDoS of this length strains any provider’s bandwidth, and for a Linux distribution that powers servers worldwide the impact ripples through development pipelines and automated deployments. Customers reporting delays cited stalled package uploads and broken webhook callbacks, which can halt CI/CD workflows. Canonical’s response team cited upstream mitigation partners and DNS‑level rate limiting as primary defenses. The mitigation effort also involved traffic shaping.

While the attack remains ongoing, Canonical assures that critical security updates continue to be delivered via signed mirrors, mitigating risk for production environments. Users are advised to configure fallback repositories and monitor the status page for real‑time alerts. Enterprise clients reported minimal downtime overall. The incident underscores how essential robust network shielding has become for open‑source infrastructure that underpins cloud‑native applications.
