### Infrastructure updates

- Docker Hub has added Amazon CloudFront as a CDN for image pushes and pulls,
improving reliability. You may see a new domain,
`production.cloudfront.docker.com`, in your network logs. TLS certificates for
this domain are issued by Amazon Trust Services.

Most users are unaffected. You may need to take action if your environment
uses an egress firewall with a domain allowlist, a TLS inspection proxy, or
a managed CA trust store. See the [Docker Desktop allowlist](/manuals/desktop/setup/allow-list.md)
for updated domain requirements. If you see TLS errors, ensure your trust
store includes the
[Amazon Trust Services Root CAs](https://www.amazontrust.com/repository/).
