Lightning AI takes Studio platform offline after customer credentials compromised
Lightning AI Studio (hosted ML platform)
On Oct 15 2026 at 23:00 UTC Lightning AI identified unauthorized access to credentials on its Lightning Studio platform and revoked all user access two hours later. Lightning believes certain customer credentials were used to reach customer environments and connected third-party services. Studio, Deployments, Pipelines and Drive are affected; GPU cluster rental and managed Kubernetes/SLURM are not. As of Oct 25 the platform is still inaccessible while an external firm investigates. Lightning tells all users to rotate secrets stored in Studios (such as GitHub credentials) and third-party credentials used by their VMs.
