Hi all,
We have enabled the building of Mediawiki images for the Kubernetes cluster during Scap sync operations, which includes Scap backports.
This means that during a backport window, your first backport will have to wait for the images to be built and pushed remotely. From what we've seen so far, you can currently expect this to add 3-6 minutes to the operation.
We are going to continue working on the feature and hopefully bring that extra duration further down, but for the time being please be aware of the extra time when performing a backport.
Best
