Just to let everyone know, we have had to make a domain name change in
order to support an ownership issue.

The former mirror lived at mirrors.secsup.org This is no longer
maintained by our team.

The new mirror is located at mirrors.supsec.org. This mirror can be
reached via http, ftp, and rsync.

Please update any instance of secsup to reflect the new domain name.
