I've just set up a new rsync mirror.
The adress is
Bandwidth: 768/128 kbit/sec (adsl in germany)
Userlimit: 10 (as i have no experience how much bandwidth is used)
Restrictions: none (as far as i know :-) )
Server is online 24*7, ip is dynamic as the real ip changes every 24
hours. Server is updated every 30 minutes as shown in the howto.
