What happened?

Live tests on desktop browsers, mobile emulators and mobile simulators failed to start.

Why did it happen?

We deployed an update to our VM configuration and management software that inadvertently prevented our in-browser live testing client from starting new sessions.

How was it resolved?

Our monitoring systems detected the issue and the deployment was rolled back.

What are we doing to prevent it from happening again?

We are simplifying the complexity of our VM configuration and management software and implementing additional unit tests for the affected components, as well as further improving monitoring and alerting.
