The Interrupt window defines when Appliance can update its systems. When Appliance is updating, this may result in an interruption to existing connections. Set up a time window that minimizes disruption to your sites.

1. Log in to [Cloudflare One](https://one.dash.cloudflare.com/), and go to **Networks** > **Connectors**.
2. In **Appliances** > **Profiles**, select the Appliance for which you want to set up the update window > **Edit**.

1) In **Interrupt window**, select the most appropriate time for the Appliance to update its systems:

   * **Timezone**: Select the time zone for the Appliance to update.
   * **Start time**: Choose an hour for the Appliance to start updating. Cloudflare recommends you choose an hour when there is minimal activity in your network, to avoid potential disruptions.
   * **Duration**: Duration indicates the time window during which the Appliance is scheduled to update. For example, if you configure your Appliance to update at `22:00` and specify a **Duration** of `4 hours`, the Appliance will attempt to update within the four-hour period following `22:00`.
