Hello,
We tried the upgrade and unfortunately had to rollback.
The operation itself went smoothly (rsync, puppet, dns) but we have hit
an issue with Jenkins no more being able to allocate an instance to run
jobs on.
I suspect it might be related to the java upgrade (8 to 11). I will try
to find the root cause and we will schedule a new maintenance window.
For patches missing a CI result, you can retrigger it by commenting in
Gerrit "recheck" or for changes that had Code-Review +2, remove your
vote and apply it again to trigger the test and merge.
Sorry for the inconvenience.
