Repository mirroring
We mirror all GitHub repositories tagged with govuk to AWS CodeCommit every 2 hours using a Concourse pipeline configured in alphagov/govuk-repo-mirror.
The mirror allows us to continue deploying if GitHub is unavailable, and also gives us a private place to develop fixes for security vulnerabilities before they are deployed.
If GitHub is unavailable, you can still get access to Jenkins and deploy from AWS CodeCommit.
