 [cloud-platform-infrastructure repository](https://github.com/ministryofjustice/cloud-platform-infrastructure) is our main repository where infrastructure gets created and all components fit together. From this repository everything gets linked.
 
-Mostly all components are Terraform [modules](https://developer.hashicorp.com/terraform/language/modules), and they are managed in their own git repository; you can list all modules [here](https://github.com/ministryofjustice?q=cloud-platform-terraform&type=&language=).

 ## Making Changes to cloud-platform-infrastructure
 
 1. Create a PR which includes the change you want to make. Make sure the [plan pipeline](https://concourse.cloud-platform.service.justice.gov.uk/teams/main/pipelines/infrastructure-live/jobs/terraform-plan-infra-live/) is happy with the change. It is good practice to link the PR to the issue that describes the change.

 3. For certain changes, pausing the infrastructure apply pipelines and running them individually is favourable. If you are pausing bootstrap and infrastructure pipelines, be sure to communicate this in the team slack channel.
 4. Merge and wait until the [apply pipeline](https://concourse.cloud-platform.service.justice.gov.uk/teams/main/pipelines/infrastructure-live/jobs/terraform-apply-infra-live/) applies your change.

-Within the environments repository, we have an end to end process fully automated with pipelines. Once the change is merged, it is going to be automatically applied by the apply pipeline ([apply-live](https://concourse.cloud-platform.service.justice.gov.uk/teams/main/pipelines/environments-live/jobs/apply-live) and [apply-namespace-changes-live](https://concourse.cloud-platform.service.justice.gov.uk/teams/main/pipelines/environments-live/jobs/apply-namespace-changes-live/builds/1) and if the change is destroying a namespace it will be detected by [detect-deleted-namespace](https://concourse.cloud-platform.service.justice.gov.uk/teams/main/pipelines/environments-live/jobs/detect-deleted-namespaces/builds/1) pipeline.

 ## Communications
 
-If any changes involve downtime we must inform teams about it via Slack (#cloud-platform-update). It is important to include **which services** are going to be down and **for how long**.

-Sometimes teams misinterpret downtimes of Cloud Platform services to involve downtime of **their services**, so it is very important to be precise about the change and it's potential impact.
