To: debian-www@lists.debian.org

Hi,

I want to tell you that both Iranian vendors of Debian Discs are closed
some years ago, you can delete them from this list:
https://www.debian.org/CD/vendors/#ir

Best Regards

I have have checked both http://linuxcd.ir and http://linuxshop.ir and both are not online any more, so commenting these out.
