Re: [rhelv5-list] RHN CDN has a broken rhel-x86_64-server-supplementary-5 metadata file



This was resolved yesterday morning.

My frustration level was enhanced by problems creating a new support case. That issue no longer exists (whether it was an actual RedHat customer portal issue or a transient bug in my browser, I don't know).

The general troubleshooting/workaround points remain valid:

1) You almost always want "Location-aware updates" turned on because downloads will be faster.

2) If you have that turned OFF, then downloads always come from xmlrpc.rhn.redhat.com with a stable IP address.

3) At this time, the technical meaning of "Location-aware updates" is that the client does a DNS lookup for content-xmlrpc.rhn.redhat.com, which will return a different proxy server in the Akamai cloud depending on your DNS server's network location.

4) Circumstances where you want "Location-aware updates" turned OFF include:
   a) A strict default-deny outbound firewall policy, such that you need the stable destination IP address
   b) Transient failure of portions of the RedHat/Akamai content delivery network(s), as in this case
   c) If your DNS server is non-local, and you know that xmlrpc.rhn gives better performance than content-xmrlpc.rhn (rare)

5) Another possible workaround is to obtain another IP address for content-xmlrpc.rhn.redhat.com from a different ISP's DNS server and stick that in /etc/hosts.
