Scheduled Maintenance Windows for License Servers

Organization administrators can now choose when Rescale applies operating system security updates to their Company License Proxies. Patching a proxy sometimes requires it to reboot, which briefly interrupts license traffic passing through it. Setting a maintenance window puts that interruption on a weekly schedule you pick, rather than leaving it to an arbitrary hour.

License Hosts have supported maintenance windows since August 2025. This release brings the same control to Company License Proxies.

Highlights

  • Pick your own weekly window: Choose the day of the week and the hour (UTC) when maintenance may begin on each License Proxy, set independently per proxy.
  • Required for FedRAMP Moderate organizations: If your organization has one or more FedRAMP Moderate compliant workspaces, your License Proxies now have a maintenance window. Every other organization can configure one optionally, and we recommend it — a proxy without a window does not receive security updates.
  • More reliable window changes: Moving a proxy’s window to a different day or hour now saves correctly every time. If you changed a window before June 2026 and found it reverted afterwards, set it again and confirm it holds.

Getting Started

Open your Organization Administration Portal and go to Integrations → License Proxy, then select the proxy you want to configure. In the Maintenance Window Schedule section, click Edit, choose the day of the week and the hour, and click Update.

Times are 24-hour format and always UTC — they do not follow your local time zone and do not shift with daylight saving time. Pick an hour when you do not normally have long-running licensed jobs in flight. If you have several proxies, consider staggering their windows.

The day and hour you choose is when maintenance may begin. Updates are applied only if any are pending, so a reboot does not happen every week — and Rescale does not send advance notice when one does. That is why the window you choose matters.
