    Due to a recently disclosed critical security vulnerability affecting Linux kernel-based virtualization platforms, we are implementing preventive security measures.

    As part of these maintenance activities, UT Cloud virtual machines (VMs) will be restarted. The VMs will be brought back online in a rolling manner over the next couple of hours. Besides virtual machines, some websites are also affected. In case of questions, please contact us at support@hpc.ut.ee.

    We apologize for any inconvenience and appreciate your understanding as we work to ensure the security and stability of our platform.
