What happened:

Automated tests in our virtual device cloud that were configured to use the latest Chrome browser version experienced an increased session start time or elevated error rate in both the EU and US regions. 

In these scenarios, users saw the following error messages:

• Infrastructure Error -- The Sauce VMs failed to start the browser or device.
• Session did not start. User might have disconnected. 

Why it happened:

A new Chrome browser release process left some stale images/VMs unable to handle the latest release of the Chrome browser. Customer tests configured to run on the “latest” version of Chrome began experiencing issues.

How we fixed it:

Once we were alerted to this condition, we decided to revert the latest Chrome browser release from production environments.

What we are doing to prevent it from happening again:

We are reviewing the browser promotion and adding code safeguards in how images/browsers are released into our production.
