You're right, looks like the bots are down. All 7 devices are connected to the same host, so must be the host.

+maruel, should Swarming give NO_RESOURCE in this scenario?

Sample Swarming task:

Yes, it's a false negative.

I believe these were caught by the auto device tickets:
https://gutsv3.corp.google.com/#ticket/34075155

BTW, this looks to be a bot on the -b4 vlan connected to the internal swarming server:
https://chrome-swarming.appspot.com/bot?id=build128-b4--device1

That's probably not good, right? (If that's harmless, then ignore me.)

Device #6 needed to be replaced.  rebooting and flashing of the phone didn't bring it back.  

Device #3 was rebooted and looks healthy. 

Passing this bug on to johnw to reinstall and move this bot from b4 to b7

I can look into migrating this today.

Thanks.

Apologies, need to push this to tomorrow.

Thanks.

Docker and pools have been migrated and the devices are in swarming.

Thanks.
