 > As the global custom IP prefix transitions to a **Commissioned** state, the range is being advertised with Microsoft from the local Azure region and globally to the Internet by Microsoft's wide area network under Autonomous System Number (ASN) 8075. Advertising this same range to the Internet from a location other than Microsoft at the same time could potentially create BGP routing instability or traffic loss. For example, a customer on-premises building. Plan any migration of an active range during a maintenance period to avoid impact.
