Hello dear contributors,
We identified the source of slowness: it seems that the downloads from
repo.jenkins-ci.org are really really slow.
JFrog had been contacted and we are waiting for feedback from them to fix the issue.
We'll answer back there as soon as we have more informations.
Please note that your local builds could also be impacted (if you do not have the artefacts on your local build cache).
For the infra team,
Damien Duportal
