Greetings folks, This is just a reminder notice that this maintenance window is happening this coming Saturday and to also note that it has been expanded by 1.5 hours on the front end since there is a hardware issue that needs to be addressed before the OpenStack upgrade happens.
Times have been updated in the subject and original body accordingly. -Andy- On 11/09/2016 11:07 AM, Andrew Grimberg wrote: > What: Rackspace will be performing an upgrade of OpenStack on the > private cloud that OpenDaylight uses for CI.
