This makes me think of the AMQP stuff DSA has setup as well as the fedmsg bus.

debsecan exists (and daily mails the sysadmin about new security
updates, available security updates, fixed security issues and
security issues without updates) but it only prints errors in the
download process when run interactively:


I suppose the reason is that the Internet is flakey and this would
guarantee to annoy sysadmins world-wide, which might make them remove
or turn off debsecan.

apt already supports this.

This is already the case, but it has a longer validity period:

10 days: http://security.debian.org/dists/wheezy/updates/Release
7 days: http://ftp.debian.org/debian/dists/wheezy-updates/Release
7 days: http://ftp.debian.org/debian/dists/jessie/Release

That sounds like it would introduce a denial of service attack.
