(No hurry, :D) Please have a look at http://www.debian.org/mirrors/official#criteria (ftpsync + rsync + push) Last but not least: ------------------- 5. http://mirror.bjtu.edu.cn/debian/project/trace/debian.bjtu.edu.cn still says ftpsync is not used. 6. http://mirror.bjtu.edu.cn/debian/project/trace/ 3 days late, but I guess this is due to the slow network. -- Simon Paillard -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
