Comment (by raimue):

 It is not about a timeout in the HTTP request, it looks like DNS failed.

 If the upload failed, just wait for 30 seconds and then try again. Do that
 three times. As you can see in the logs, the next fetch worked again, so
 the network problem must have been quite short. That would not add that
 much to risk a build timeout.
