According to Chinese regulation, all web services(listen on 80 and
443) should be register to government sector. For Debian is not a
Chinese entity, it may be not possible to complete such registration
legally. USTCLUG, the maintainer of ftp.cn.debian.org, anounced [1]
that ftp.cn.debian.org services is stoped. ftp2.cn.debian.org still
works but I think they will face the same problem.
I advice change ftp*.cn.debian.org dns record to other mirror site
outside Chinese mainland before the domain name registration problem
be resolved. so that our end user will not be affected by this
problem.
