On http://www.webqa.redhat.com, click on the store link in the global header and you will get a 500 error.
Now I am getting a message about the Interchange server being down or too busy to handle my request. IC is not on webqa, so I should not be getting this. The Global Header is going out before the IC implementation, so this link still needs to take the user to the old store.
OK, link on webqa is now taking me to the old store, so that's good. Closing out this issue.
