Describe the documentation issue

The Docker registry at 54.204.128.201:5000 appears to be down.

Also, this section
`docker info
You should see the following output:

Insecure Registries:
52.3.255.136:5000
127.0.0.0/8`

Refers to a different (also down) private registry.

What solution would you like to see?

Clarification of correct Docker private registry address, and resolution of private registry availability.
