Around September 18th, EMCO CI stopped verifying each and every patch (unrelated to DCM). The cause, a dependency of an old version of an EMCO's dependency (operator-sdk) was removed from the repository there set.

Here is how the problem manifested:

(Monitor was just one of the affected services)
