Google OnHub and WiFi Devices Temporarily Knocked Offline, Reset ⇥ support.google.com

From a February 23 help document:

Today we experienced an issue with our Google Accounts engine that may have affected your Google Wifi or OnHub device. This caused some devices to automatically reset to the initial state you bought them in. Unfortunately, these devices need to be set up again. We’d like to share our sincerest apologies for the inconvenience.

On the same day, a bunch of users also reported that they were being signed out of their Google accounts. Very strange and, in the wake of yet another “internet of things” vulnerability, concerning.
