Due to firewall rules there is bandwidth management and it allows
downloads to start at a high speed only to slow down at 25MB.
You could game the bandwidth management with wget or curl, using their
continuation capability. When the throttling starts, stop the program,
wait a few seconds, and then restart with the continuation option.
That way, you download the large file in several 25 MB chunks at high
speed. Only useful for occasional large files, not in general, though
you could script it. Put the downloaded file in the local yum
repository (under /var/yum somewhere) where yum will find it when it
tries to update, or install it directly using the -C option.
The Question.
The network admin asked if Fedora was like Ubuntu that will continue
downloading where it left off? I stated I doubted it as the display
kept going back to zero
This has been my experience as well. Internally, I think yum uses
python-urlgrabber to fetch the packages, and it seems to have no
memory of past attempts.
There is probably a reason this behavior was adopted, but I don't know
it.
You might be able to use the throttle and bandwidth options to adjust
for your bandwidth management. See man yum.conf.
