Setup Debian Mirrors after Installation
debian
You just want some mirror or the closest/fastest mirror. If it's the latter, then you could just install netselect-apt and run it. I just ran to see which are the fastest form my geographical location and it said -[$] sudo netselect-apt testing................    The fastest 10 servers seem to be:        http://mirrors.ispros.com.bd/debian/        http://ftp.sg.debian.org/debian/        http://mirrors.apu.edu.my/debian/        http://ftp.iinet.net.au/debian/debian/        http://debian.mirror.cambrium.nl/debian/        http://mirror.sax.uk.as61049.net/debian/        http://ftp.uk.debian.org/debian/        http://mirror.vorboss.net/debian/        http://mirror.1000mbps.com/debian/        http://ftp.antik.sk/debian/    Of the hosts tested we choose the fastest valid for HTTP:            http://mirrors.ispros.com.bd/debian/    Writing sources.list.    sources.list exists, moving to sources.list.1484862805    Done.[$] cat sources.list.1484862805     1  # Debian packages for testing     2  deb http://debian.ec.as6453.net/debian/ testing main contrib     3  # Uncomment the deb-src line if you want 'apt-get source'     4  # to work with most packages.     5  # deb-src http://debian.ec.as6453.net/debian/ testing main contrib     6       7  # Security updates for stable     8  # deb http://security.debian.org/ stable/updates main contribHope you find it useful.
