 We've updated [preview URLs](/workers/configuration/previews/) for Cloudflare Workers to support long branch names.
 
-Previously, branch and Worker names exceeding the 63-character DNS limit would cause alias generation to fail, leaving pull requests without aliased preview URLs. This particularly impacted teams relying on descriptive branch naming.
+Previously, if your branch name or Worker names exceeded 63 characters, no preview URL was created. This happened because each preview URL exists on its own subdomain, and the DNS record for a subdomain cannot be longer than 63 characters.
 
 Now, Cloudflare automatically truncates long branch names and appends a unique hash, ensuring every pull request gets a working preview link.
