Zephyr Project systems maintenance November 12, 2016 @ 08:00 - 10:00 PT

What: The cloud provider for the CI infrastructures that Zephyr uses
will be migrating instances between availability zones (AZ) as they work
on decommissioning the AZ that some instances are currently residing in.
While they are doing this work The Linux Foundation will be remanaging
the VPN network link between the cloud and our core datacenter.

When: November 12, 2016 (2016-11-12) @ 08:100 - 10:00 PT (16:00 - 18:00 UTC)

Why: Our cloud provider needs to migrate the JIRA and Gerrit instances
between availability zones as they continue their process to
decommission the AZ that the nodes are presently in.

Additionally The Linux Foundation needs to make changes to the current
VPN endpoint that links the CI cloud with our core datacenter so that we
can realize some management improvements.

Impact: JIRA and Gerrit will be offline while the instances are being
migrated. Jenkins will be configured to be in shutdown mode from a bit
before outage till the updates are done so that we can avoid jobs
getting erroneous results due to the missing Gerrit instance.

There will also be minor network outage that impacts Jenkins and Nexus
as we make the needed changes to the VPN endpoint.

Lastly there will also be an IPv4 / IPv6 change as we change VPN
endpoints. This will be noticeable by new SSH addresses being added to
known_hosts during git operations. This final change may be rolled in
early as it is possible for us to do part of this transition without
downtime.

Outage notices will be sent to the mailing lists as well as on
#zephyrproject on Freenode before and after the maintenance window.
