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


Friday September 1st 2022, 16:00 - 17:57 UTC

What happened:

New test requests in all regions began to queue up in “new job” status waiting for the system to allocate them to test resources. The spike in queued test requests was detected by our internal alerting system. 

Why it happened:

An application deployment introduced a bug that caused an unrecoverable error in the resource allocation process. 

How we fixed it:

We reverted the deployment to the previous version. 

What we are doing to prevent it from happening again:

We are evaluating ways to better detect an issue like this through better test coverage in our development process.
