Starting August
15, 2025, Azure Front Door (classic) and Azure CDN from Microsoft Classic SKUs
will no longer support new domain onboarding or profile creation.
Additionally, DigiCert is deprecating
CNAME-based Domain Control Validation (DCV) on the same date, aligning with the
industry-wide transition to Multi-Perspective Issuance Corroboration (MPIC). As
a result, switching from Bring Your Own Certificate (BYOC) to managed
certificates on existing domains will no longer be supported for these classic
SKUs. Existing managed certificates will auto-renew before August 15, 2025, ensuring no service disruption until April 14, 2026.
Required
action
- If you want to use managed
certificates or create new domains/profiles, migrate to one of Azure Front Door
Standard or Premium SKUs before August 15, 2025.
- If you are already using Azure managed certificate on existing domains move
to Bring Your Own Certificate (BYOC) or
migrate to one of Azure Front Door Standard or Premium SKUs before August 15, 2025. Please refer to Configure HTTPS for your custom domain for details.
