Unity Build Automation - Builds failing to start

We have monitored builds and they are now starting as expecting.

We have released a hotfix to resolve the issue. We will continue monitoring to ensure that builds are running without issue.

Builds across Mac and Windows machines are unable to start. Builds fail when attempting to retrieve the latest version of Unity Build Automation tools. The builds are failing prior to the billable portion of a build.

We are currently investigating the root cause of this issue.
