We've made some good progress with transferring the staging VMs
and services are coming back online now.  In principle all of
staging should be back to normal by tomorrow.

Also:

* https://chromeos.kernelci.org (ChromeOS KernelCI instance)

The ChromeOS instance relies on services running both on staging
and production so it will be affected by both updates.  On a side
note, we're now working on removing this dependency with a new
chromeos.staging.kernelci.org instance for ChromeOS KernelCI
development purposes - this will happen after the move to the new
Azure subscription.

We're going to have a short production downtime later today to
take a copy of the VMs.  The web dashboard shouldn't be down for
more than a few minutes, and there might be some extra lag before
some kernel git revisions start getting tested.  This should help
reduce the downtime needed on Monday to complete the production
move.  We'll keep sending updates as things progress.
