Then we need to verify that this actuall resolves the issue (i.e. if the 429 continues we may want to flag backpressure on a per upstream basis from the registry so that all clients slow down).

Hi Ricardo, Do you have idea how to reproduce this bug?
Increasing severity and priority as this problem complicates investigation of CI problems. For example, BZ 2026104.
I have tested https://github.com/openshift/image-registry/pull/273 and although it seems to address the original error, now I'm getting a different. Looks like there are other places we need to handle the 429 from the origin registry before it can make its way to the client. I'm investigating.
