Each time a CL is reviewed and submitted, the site is automatically deployed to App Engine. If the CL is submitted with a Website-Publish +1 vote, the new deployment automatically becomes https://golang.org/. Otherwise, the new deployment can be found in the App Engine versions list and verified and manually promoted.
If the automatic deployment is not working, or to check on the status of a pending deployment, see the “website-redeploy-golang-org” trigger in the Cloud Build console.
