Project Default Hostname NXDOMAIN Despite Healthy Dashboard Status

User reports project gcizehgpcztmqtqhveng is healthy in dashboard but its default supabase.co hostname resolves to NXDOMAIN; DNS record missing or not propagated.

Origin Analysis

Provisioning pipeline completed internal service deployment but failed to register/publish the project's public DNS record, and health checks do not validate external DNS resolution, allowing a false healthy state.
1. Create or access project gcizehgpcztmqtqhveng in Supabase dashboard. 2. Observe dashboard shows 'Healthy'. 3. Query DNS for gcizehgpcztmqtqhveng.supabase.co using nslookup/dig. 4. Observe NXDOMAIN / ERR_NAME_NOT_RESOLVED from multiple resolvers.

Fixing Code Block

Edge Case Audit

Requires correct hosted zone ID and target CNAME; incorrect target can direct traffic to wrong endpoint. Use dry-run, backup existing records, and test in staging. Not a permanent fix: provisioning pipeline must be updated to verify DNS and auto-repair. Rollback: delete the created record if issues arise, or replace with correct target.
