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


Thursday September 28th 2023, 17:05 - 17:36 UTC

What happened:

For the duration of the incident, customers could not start new tests in all regions. 

Why it happened:

A change that removed public cloud provider storage interfaces from the core Kubernetes codebase was introduced during a Kubernetes upgrade. We needed to rework large sections of our infrastructure management code to handle this change. In making these changes, we introduced an issue with applying firewall tags that broke key traffic outside the Kubernetes cluster.  This was not detected in lower environments. 

How we fixed it:

We manually rolled back the configuration that caused the issue. 

What we are doing to prevent it from happening again:

We are addressing the underlying issue that caused the broken cluster networking. Once we have that fix we will plan a safe rollout.
