Note: After your resource has been created, we need some information to verify your network operator status and approve you to host Microsoft Connected Cache nodes. Please ensure that your Peering DB organization information is up to date as this information will be used for verification. The NOC contact email will be used to send verification information.
Enter your organization ASN. Indicate whether you're a transit provider. If so, additionally, include any ASN(s) for downstream network operators that you may transit traffic for.
Once we verify the information entered, a verification code will be sent to the NOC email address provided on Peering DB. Once you receive the email, navigate to your Azure portal > Microsoft Connected Cache > Settings > Verify operator, and enter the verification code sent to the NOC email address.
