Actually auron_yuna-release is offline too. gnawty, peppy and expresso are also marked as offline on the waterfall but don't actually seem to be offline?

Filed issue 819417 for novato-release.

auron_yuna-release is cros-beefy13-c2.
betty-arc64-release is build221-m2, using issue 819417 for that as well.

lakitu-gpu-paladin has build199-m2, which is down. But is has redundancy.

I've restarted cros-beefy13-c2, and auron_yuna-release is back.

Filed  issue 819419  as follow up for cros-infra to get alerted on this condition.

novato-release is offline again, assigning to infra deputy
