new setup.exe - another problem, or is this behavior expected?

[carolus]

On my last download, a few days ago, when the initial server became 
unresponsive, the setup process simply hung up even though I had 
selected several alternate servers.  After waiting a while, I terminated 
and restarted the process but again the process hung up.  I had to 
remove the offending server from the selected list to get the download 
to proceed.  However, when I did so, it downloaded a lot of duplicates 
of files already downloaded from the failed server.

This is not what I expected on the basis of past experience, but the 
installation instructions simply state: "You can select multiple mirrors 
by holding down CTRL and clicking on each one." with no explanation of 
the expected consequences.

I asked for an explanation but have gotten no response:

Good that you persevered then. :-)

I do believe the point of supporting multiple server selections is to allow
you to add servers with differing package sets.  Cygport comes to mind.  If
you're choosing multiple Cygwin mirror servers and expecting fault
tolerance, I'm afraid you're looking for allot more than setup's equipped
to deliver.  ;-)  In addition, if you start one session of setup, select a
package, download it, and don't install it (for whatever reason), then
start another setup session and do the same thing with a with a different
mirror, you'll get the same package again under a different directory tree
(the root of that tree being loosely named after the mirror you chose).  So
the moral to the story is that you shouldn't select more than 1 mirror
unless you know there's something in one that's not in the other and
preferably there's no overlap.

Does this mean that install-from-internet is a better choice than 
download-without-installing when the connection is apt to be broken? Or 
for combining several overnight runs to cope with a slow connection? 
Currently I'm downloading to an external USB drive which I then use to 
reinstall Cygwin on several machines.

And thanks for the explanation.

Either should work OK, as the former is a superset of the latter.  The key
thing is to not pick more than 1 mirror if you don't need to.

Heh, I wasn't even aware that the list of mirrors is multi-select, and
I used it daily for 6+ years.
