With the recent infra refactorings, the update center job was moved into the secured Jenkins instance.
While I totally understand the reasons, in that case this makes helping plugin developers harder, almost impossible actually.
The typical question we have, as you know, is "I released my plugin and it's not available, did something go wrong?".
Before, we were available to crawl the UC build logs to find out if, say, it was ignored because of a missing wiki page, and so on.
Today, we're unable to analyse it and have to bother one of the admins to know more about that.
I'm not (necessarily) asking for access to that private Jenkins instance, but more of any way we could make those logs securely accessible for everybody (to let people find out the solution by themselves, granted we document how to do it w/ the wiki).
