 ### DNS propagation
 
 DNS changes typically take 1-24 hours to propagate globally, though it can take up to 48 hours in some cases. You can verify your DNS is configured correctly using [DNSChecker](https://dnschecker.org).
 
 Once your DNS records are active, your documentation is first accessible via HTTP. HTTPS is available after Vercel provisions your TLS certificate.

 ### Reserved paths
 
 The `/.well-known/acme-challenge` path is reserved for certificate validation and cannot be redirected or rewritten. If you have configured redirects or rewrites for this path, certificate provisioning fails.
