Description of issue: Cloud build is repeatedly hanging/failing at the project checkout stage. Builds will get stuck on the “GIT: Checking out…” line and will eventually be cancelled by the build system after many hours. For the last 3 days this is occurring about 50% of the time. Our project is hosted on Bitbucket as a Git repository. Bitbucket reports no service outages, and we haven’t had any problems using the repo in this period.
EDIT: I’ve moved the details to a support ticket (https://support.unity3d.com/hc/requests/767332).
