 ### Public peering
 
-Public peering has been disabled on new ExpressRoute circuits. Azure services are now available on Microsoft peering. If you have a circuit that was created before public peering was deprecated, you can choose to use Microsoft peering or public peering, depending on the services that you want.
+Public peering is no longer available on new ExpressRoute circuits and is scheduled for retirement on March 31, 2024. Access to Azure services can be done through Microsoft peering. To avoid disruption to your services, you should migrate to Microsoft peering before the retirement date.

 ExpressRoute lets you extend your on-premises networks into the Microsoft cloud over a private connection with the help of a connectivity provider. With ExpressRoute, you can establish connections to Microsoft cloud services, such as Microsoft Azure and Microsoft 365.
 
 Connectivity can be from an any-to-any (IP VPN) network, a point-to-point Ethernet network, or a virtual cross-connection through a connectivity provider at a colocation facility. ExpressRoute connections don't go over the public Internet. This allows ExpressRoute connections to offer more reliability, faster speeds, consistent latencies, and higher security than typical connections over the Internet. For information on how to connect your network to Microsoft using ExpressRoute, see [ExpressRoute connectivity models](expressroute-connectivity-models.md).
