-In the classic service tiers, Azure API Management offers [free, managed TLS certificates for custom domains](../configure-custom-domain.md#domain-certificate-options), allowing customers to secure their endpoints without purchasing and managing their own certificates. Because of an industry-wide deprecation of CNAME-based Domain Control Validation (DCV), our Certificate Authority (CA), DigiCert, will migrate to a new validation platform to meet Multi-Perspective Issuance Corroboration (MPIC) requirements. This migration requires a temporary suspension of managed certificates for new custom domains.
