This hierarchy contains various items of interest in TeX history, from individual files to entire systems. See the TUGboat article by Ulrik Vieth for an overview.

Mirrors

The master is at (DE, Bavaria):

and it is mirrored at (US, Utah):

and (FI):

and (DE, Chemnitz):

and (DE, Erlangen-Nürnberg):

and (CN, Beijing):

and (CN, Nanking):

More mirrors are welcome; cron rsync -a --delete rsync://tug.org/historic/
and email webmaster at tug.org when it's set up. Thanks.

Using a mirror is recommended. The tug.org server has strict limits on the number of ftp connections, so if you have trouble connecting (e.g., to get an old TeX Live or MacTeX), please try one of the mirrors. Nowadays, few browsers support ftp, and the ones that do generally report some vague problem on the server when the actual issue is too many connections. Your best bet is rsync from the command line.

If you are looking to update an old version of TeX Live, please see this past releases section on the TL web pages. They are under the directory systems/texlive/ here.
