Emergency Security Maintenance – Windows Hypervisor Host Nodes

Identified

Affected

  • IdentifiedUTC

    Microsoft has just released security updates for several Critical vulnerabilities affecting Windows Server, including the Hyper-V platform our host nodes run on. To protect customer workloads, we are applying these updates to all host nodes on an emergency basis.

    Start: Immediately
    Expected impact: About 40–60 minutes per server. We’re patching host nodes in batches, so not all servers will be affected at the same time.

    Your server will be unreachable during maintenance. It will not be restarted, and everything running on it will continue as normal once maintenance is complete.

    Recommended action: Depending on the Windows features and services running on your server, these vulnerabilities may also affect it. We strongly recommend installing the latest Windows updates on your server as soon as possible.

    We’ll post an update here when all host nodes are patched. If you have any questions, please open a support ticket.
