[QA] CI maintenance on Thursday 3rd Nov 16:00 UTC

Thu Oct 27 20:44:46 UTC 2016

The Wikimedia continuous integration system will be unavailable while some
scheduled maintenance is done.

When: Thursday 3rd 2016 for two hours between 16:00 UTC to 18:00 UTC.

Impact: During that time, you will still be able to send patches to Gerrit but
no CI jobs will be run nor will patches be automatically merged when someone
votes "Code-Review +2". All patches sent during the operations will be sent to
the CI system for you as a convenience.

Why: The maintenance will move the core of the CI system (Jenkins and Zuul)
from an aged server to a fresh new machine.

More info: It will be done by Antoine Musso, Tyler Cipriani and Daniel Zahn.
You will be able to watch progress on IRC in the #wikimedia-operations channel.
