Start by reviewing build runs 33671638017, 34432786645, and 34519005883, focusing on the listed Windows and macOS test jobs and their artifact-upload steps. Compare the runner and network conditions around each ETIMEDOUT failure; done means the affected CI jobs can upload artifacts reliably or the failure is otherwise handled and verified in a rerun.
