Use when: (1) fastly domain-v1 create succeeds but domain returns 500, (2) Domain shows activated:false in API response, (3) Classic domain API returns "deprecated" error, (4) Custom domain works on edgecompute.app but not on your domain.

Fastly Domain-v1 Activation for Compute Services

Problem

After creating a custom domain with fastly domain-v1 create --fqdn example.com --service-id XXX, the domain returns a 500 error: "Fastly error: unknown domain: example.com. Please check that this domain has been added to a service." The edgecompute.app URL works fine.

Context / Trigger Conditions

• Classic domain API returns: "The classic domains APIs are deprecated. Please use the domain management API"
• fastly domain-v1 create succeeds with domain-id and service-id
• HTTP request to custom domain returns 500 "Domain Not Found"
• Checking domain via API shows "activated": false, "verified": false
