How do I find where a build/test job is running?
The best approach is the examine the job on treeherder. Click on the job you're interested in, and look at the information on the bottom-left. Taskcluster jobs have [TC] in their name. They also have "Machine: unknown". Buildbot jobs have specific machine names specified, e.g. "Machine: bld-linux64-spot-134"
