We are experiencing an intermittent issue in our US-West-1 datacenter that causes elevated wait times and error rates when starting desktop browser and virtual mobile device tests. Until we address the underlying causes of this issue, we expect this issue to continue to reoccur. We will post incidents here on our status page as each instance of this issue occurs whilst we continue to work to address the underlying cause.

Incident Report for Sauce Labs


Thursday, December 1st 2022, 02:08 - 04:05 UTC

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.
