78-79: Clear and well-placed operational guidance.

The warning note is appropriately positioned immediately after the ProviderNetwork/Vlan configuration example and communicates the critical operational constraint (connectivity interruption during individual resource modifications) with actionable guidance (plan changes during maintenance windows). The formatting is consistent with existing documentation conventions and the message is concise and professional.
