Typically, upgrades and routine maintenance tasks are performed without any service impact.
Periodically, a maintenance window affecting the service is required. This window allows Trend Micro to perform specific planned maintenance tasks. Trend Micro provides at least 7 days notice prior to any scheduled maintenance.
To be notified of scheduled maintenance, subscribe to the Trend Cloud One maintenance RSS feed feed-icon=6b79a3a6-d5e2-4b37-8c17-02972dbffb4d.png.
