I think part of the problem is also that many sites mirror other mirrors
instead of the main site. Some of these "mirrors" have bad/incomplete
copies and the errors get propagated on.. possibly with additional missing
files.
I finally did get a complete 8.1 copy a few days ago. Now the fun part
is to keep MY copy up to date.
I am not sure exactly how Slackware is "released" .. but if what I think
happened is what happened, in the future, there should be a way for them
to make sure that at least a few of the major mirror sites get the new
release BEFORE the announcement is made to the world that a new release
is out.
This is especially important in cases like this where the main site does
not have sufficient bandwidth to handle the load. Even if you can connect
directly to ftp.slackware.com the download speed were so slow, it was
impractical to really do anything. Dowloading a 650 MB file at 4K bytes/sec
comes to about 45 hours of download time. No way!!
When I finally did get through to a decent mirror, I got the entire ~2 GB in
about 2 hours or so..
It would also help if the list of mirrors at
www.slackware.com was more
up to date. Many missing. Many that no longer work.
