Sauce Labs Maintenance Windows for Sauce Labs
We are investigating an issue with a third-party provider that is causing intermittent "Connection timed out", "pool communication" and "Unknown error while proxying appium request" errors when running tests in our EU and US datacenters. We will be performing emergency maintenance to our EU-Central and US-West datacenters this week to address this issue. Emergency maintenance windows will be posted to this page.

Incident Report for Sauce Labs

What happened:

Customer’s automated tests in our virtual device cloud that were using the latest Chrome version experienced an increased error rate in both the EU and US regions. The message customers received was as follows: Misconfigured -- Unsupported OS/browser/version/device combo: (OS: 'Linux Dev', Browser: 'googlechrome', Version: '107.0.5304.68', …

Why it happened:

The team that manages browser versions usually deploys new browsers in a hidden mode that allows them to test the new browser before they are made generally available to all customers. During a deployment, a pre-release of Chrome browser happened without this hidden tag being applied. 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 removed the pre-release version of Chrome browser 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 dev images/browsers are released into our production.
