Hello,
We had a short downtime of CI between roughly 3am and 9am UTC that caused roughly 2/3 of triggered jobs to fail cloning.
The reason is we deployed additional zuul-merger instances (which takes your patches, merge it on tip of branch and then expose the result to jobs) but the git-daemon exposing the repositories was not started.
I respawned the git-daemon and it all works properly now. I am doing a recheck and CR+2 again all patches that got affected.
