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/.

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.
