OCI Internal Yum Repositories Not Accessible From Instance "Operation timed out after 30001"

Applies to: 

Oracle Cloud Infrastructure - Version N/A and later

Information in this document applies to any platform.

Symptoms

Yum operations show that one or more of the OCI internal regional Oracle Linux repositories is unreachable:

$ yum repolist...https://yum-<OCI-REGION>.oracle.com/repo/OracleLinux/.../repomd.xml:[Errno 12] Timeout on https://yum-<OCI-REGION>.oracle.com/repo/OracleLinux/.../repomd.xml:(28, 'Operation timed out after 30001 milliseconds with 0 out of 0 bytes received')Trying other mirror.$

Cause

/etc/yum.conf contains a proxy configuration:

proxy=http://<PROXY-IP-ADDRESS>:<PROXY-PORT>/

This causes yum to always use that proxy when connection to all repositories.

Solution

The OCI internal repositories ( are not accessible from the internet so the existing internet proxy is not able to reach them causing the timeout.
