If there's a loss of network connectivity while dogestry is transferring files to/from S3, then dogestry will just hang.

EDIT:

(My proposed solution below is wrong. I need to recognize when the transfer has stopped, not limit the amount of time that the transfer must complete in.)

The solution is to set the ConnectTimeout and ReadTimeout when creating the s3Client. Right now, both timeouts use the default value of 0, which is in effect, no timeout value at all.
