I tried two files which took about 60 and 150 minutes to download.
wget had to retry with partial data several times and completed the
downloads after a few retries. A pattern emerges from when you look
at the timestamps in the typescript of the wget jobs: apparently, a
cron job which seems to run at 17,47 minutes every hour is restarting
the web server.
