 ## What is the difference between Internet peering and Peering Service?
 
-Peering Service is a service that intends to provide enterprise grade public IP connectivity to Microsoft for its enterprise customers. Enterprise grade internet includes connectivity through ISPs that have high throughput connectivity to Microsoft and redundancy for a HA connectivity. Additionally, user traffic is optimized for latency to the nearest Microsoft Edge. Peering Service builds on peering connectivity with partner carrier. The peering connectivity with partner must be Direct peering as opposed to Exchange peering. Direct peering  must have local and geo-redundancy.
+Peering Service provides enterprise-grade public IP connectivity to Microsoft for customers. Enterprise grade Internet includes connectivity through partner ISPs that have high throughput capacity to Microsoft and redundancy for reliable connectivity. Peering Service providers receive a customer’s registered traffic directly from Microsoft at locations that are selected by the customer.
 
 ## What is legacy peering?
 
-Peering connections set up in the past are stored in our system as legacy peering which you may choose to convert to manage as an Azure resource. Any new peering connection set up using Azure PowerShell is managed as an Azure resource.
+Peering connections that were set up outside of the automated portal process and aren't shown as resources in your Azure subscription are considered legacy peerings. It's encouraged but not required to set up all peering connections in the Azure portal and to convert legacy peerings to Azure resources so that a peer can view and manage all of their peering connections to the Microsoft network. By utilizing the Azure portal, peers can also view performance metrics and submit support tickets. If a peer is interested in becoming a MAPS partner, then converting legacy peerings to Azure Resources is a requirement.
 
-## When New-AzPeeringDirectConnectionObject is called, what IP addresses are given to Microsoft and Peer devices?
+## What is the minimum link speed for an interconnect?
 
-When you use `New-AzPeeringDirectConnectionObject` cmdlet, you enter a `/31` prefix (`a.b.c.d/31`) or a `/30` prefix (`a.b.c.d/30`). The first IP address (`a.b.c.d+0`) is given to the peer device and second IP address (`a.b.c.d+1`) is given to Microsoft device.
+10 Gbps.
 
-## What is MaxPrefixesAdvertisedIPv4 and MaxPrefixesAdvertisedIPv6 parameters in New-AzPeeringDirectConnectionObject cmdlet?
+## When will peering IP addresses be allocated and displayed in the Azure portal?
 
-`MaxPrefixesAdvertisedIPv4` and `MaxPrefixesAdvertisedIPv6` parameters represent the maximum number of IPv4 and IPv6 prefixes a Peer wants Microsoft to accept. These parameters can be modified anytime.
+Our automated process allocates IP addresses and sends the information via email to the PNI requestor after the port is configured on our side. This may take up to a week after the request has been submitted as the port has been cabled before it can be configured.
+
+## What Microsoft routes will be advertised over Peering Service connections?
+
+Microsoft advertises all of Microsoft's public service prefixes over the Peering Service connections. This will ensure not only communications, but other cloud services are accessible from the same connection.

-          Can a carrier use their existing Direct peering with Microsoft to support Peering Service?
+          Can a carrier use existing direct peering connections with Microsoft to support Peering Service?
         answer: |
-          Yes, a carrier can use its existing Private Network Interconnect (PNI) to support Peering Service. A Peering Service PNI requires redundancy to support HA. If existing PNI already has diversity, then no new infrastructure is required. If existing PNI needs diversity, then it can be augmented.
+          Yes, a carrier may leverage existing Private Network Interconnects (PNIs) to support Peering Service. Additional PNIs may be required to support local and geo diversity requirements. Primary and secondary connections must have equal capacity.  In the Azure portal, carriers can request the conversion of existing PNIs to the Peering Service configuration and can also request new Peering Service connections PNIs.
 
       - question: |
-          Can a carrier use new Direct peering with Microsoft to support Peering Service?
+          What are the diversity requirements on a direct peering to support Peering Service?
         answer: |
-          Yes, that is also possible. Microsoft works with the carrier to create new Direct peering to support Peering Service.  
+          A PNI must support local-redundancy and geo-redundancy. Local-redundancy is defined as two diverse peering connections on two routers in the same facility or in different facilities in the same metro. Geo-redundancy requires that the carrier has additional connectivity at a different Microsoft edge site within the geo-region in case the primary site fails. The carrier will route customer traffic through the backup site selected by the customer.
 
       - question: |
-          Why is Direct peering a requirement to support Peering Service?
+          The carrier already offers enterprise-grade internet, how is this offering different?
         answer: |
-          One of primary drivers behind Peering Service is to provide connectivity to Microsoft online services through a well-connected SP. Direct peering is in the Gbps range and hence a fundamental building block for high throughput connectivity between carrier and Microsoft.
+          Carriers that offer SLA and enterprise-grade internet are doing so on their part of the network. However, customer traffic may use several different carrier networks before reaching the last mile that the customer has internet access contracted through. In Peering Service, Microsoft offers a higher guarantee that customer traffic will ONLY route through the Microsoft network and handoff directly to the selected carrier network, thereby receiving a full end-to-end performance guarantee.
 
       - question: |
-          What are the redundancy requirements on a Direct peering to support Peering Service?
+          If a service provider already peers with Microsoft, what kind of changes are required to support Peering Service?
         answer: |
-          A Direct peering must support local-redundancy and geo-redundancy. Local-redundancy is defined as two different paths in a particular peering site. Geo-redundancy requires that the carrier has connectivity at a different Microsoft edge site in case the primary site fails. For the short failure duration carrier can route traffic through the backup site.

-      - question: |
-          The carrier already offers SLA and enterprise grade internet, how is this offering different?
-        answer: |
-          Some carriers offer SLA and enterprise grade internet on their part of the network. In Peering Service, Microsoft offers SLA for traffic on Microsoft part of the network. By selecting Peering Service, you get end-to-end SLA. The ISP provides SLA for traffic traveling on its network from your site to Microsoft edge. Microsoft provides SLA for traffic traveling in Microsoft global network from Microsoft edge to end users application.

-      - question: |
-          If a service provider has Direct peering with Microsoft, what are the required changes to support Peering Service?
-        answer: |
-          * Software changes to identify a Peering Service user and its traffic. May require routing policy changes to exchange a user's traffic at the nearest Microsoft edge through Peering Service connection.
-          * Ensure the connectivity has local-redundancy and geo-redundancy.
+          Peering Service partners must have an Azure subscription and manage the Peering Service connections using the Azure Portal as this is where customer prefixes are registered, performance metrics are viewed, and support tickets are logged, among other features. If a provider has existing peering with Microsoft but no Azure subscription, the resources must be added to your subscription before you will be able to convert these to the Peering Service configuration. During the configuration change, Microsoft changes the policy group during a hard restart of the BGP session. No configuration changes are required on the partner’s side, unless the telco partner is supporting Peering Service for voice then BFD configuration is required.
