GitHub Actions runner cannot access ports.ubuntu.com

I'm building containers from GitHub Actions. I'm using Ubuntu Jammy (latest LTS, 22.04). Since few hours, the GitHub Actions runners cannot any more access to the domain hosting the Ubuntu packages for non AMD64 arch, ports.ubuntu.com.

How do you advise getting around this problem?

Note for ports.ubuntu.com maintainers: The IP ranges of GitHub Actions runners are available by API.

Reproduction:

1. Create a GitHub Actions pipeline
2. Add a step for build a container
3. Build your container from Ubuntu Jammy based-image
4. Execute an apt-get install command during the build
