2020-February-22 Service Incident
Incident Report for Sauce Labs US West Data Center


Saturday February 22 10:03 - 13:58 PT

What happened:,, UI, REST API, Sauce Connect tunnels and Automated Tests in our San Jose, CA datacenter were all offline.

Why it happened:

An internal service that secures communications inside our Kubernetes server stopped working.

How we fixed it:

We redeployed new certificates which re-enabled the required communications.

What we are doing to prevent it from happening again:

We are undertaking a complete audit of all platforms to identify any other certificates that are due to expire. We are also implementing monitoring and alerting around certificates within all platforms to prevent this issue from recurring in the future.
