https://uberchromegw.corp.google.com/i/chromium.perf/builders/Android%20Nexus5%20Perf%20%282%29/builds/5369 shows an offline device on the builder. The device does show up on the internal monitoring in https://viceroy.corp.google.com/chrome_infra/Machines/android_devices, but was not included in the generated ticket (https://gutsv3.corp.google.com/#ticket/26117903).

bpastene is working on a fix. I'll file bugs for the offline devices for now?
