Some Android devices on the public cloud in the US-West-1 data center were not available for running tests.
A number of devices had lost their connection to the internet, resulting in the devices being automatically disabled. Our automated cleaning and setup process was not successful in recovering and restoring internet connectivity.
We improved the logic that allows the system to reset the internet connection for devices.
What we are doing to prevent it from happening again:
We added additional monitoring steps to give us better data about when and how devices lose their connection to the internet, while also improving the wifi configuration inside of our data centers.
