This is deb.debian.org
.
This service provides mirrors for the following Debian archive repositories:
/debian/
/debian-debug/
/debian-ports/
/debian-security/
The server deb.debian.org
does not have packages itself, but the
name has SRV records in DNS that let apt in stretch and later find places.
To use it with a sufficiently recent apt, you for instance can put
deb http://deb.debian.org/debian unstable main deb http://deb.debian.org/debian-debug unstable-debug main deb http://deb.debian.org/debian-ports unstable mainin your
sources.list
.
As of October 2016 the SRV record is
_http._tcp.deb.debian.org. IN SRV 10 1 80 prod.debian.map.fastly.net. _http._tcp.deb.debian.org. IN SRV 10 1 80 dpvctowv9b08b.cloudfront.net.If you hit the server behind
deb.debian.org
directly, either because you
use an older apt or because you use a HTTP proxy that does not support SRV records,
your requests will get HTTP redirected to one of the CDN instances.
If you want to avoid the redirects, you can pick one instance directly. For instance,
this also works in your sources.list
:
deb http://cdn-fastly.deb.debian.org/debian stable main deb http://cdn-fastly.deb.debian.org/debian-security stable/updates mainThe redirection service is also available on HTTPS, so with the
apt-transport-https
package installed, you can use:
deb https://deb.debian.org/debian stable main deb https://deb.debian.org/debian-security stable/updates mainThis service is sponsored by Fastly and Amazon CloudFront.
