SQuaRE is planning a service window this coming Thursday (2015-09-03) from 1700 - 1800 project time for both the Jenkins and Buildbot CI systems. Either service may go up and down several times during the window. An announcement will be made on the hipchat Bot: Buildbot notifications and Bot: Jenkins channels when maintenance is concluded.
The primary reason for the service disruption is to implement support for RFC-56 by enabling devtoolset-3 by default [EL6 only].
