etch packages source problem?

[Deephay <tudoxxx@gmail.com>]

Hi all,

  I got some errors while doing "apt-get update":

Failed to fetch http://http.us.debian.org/debian/debian/dists/etch/main/source/Sources.gz
  404 Not Found
Failed to fetch http://http.us.debian.org/debian/debian/dists/etch/contrib/source/Sources.gz  404 Not Found
Failed to fetch http://http.us.debian.org/debian/debian/dists/etch/non-free/source/Sources.gz  404 Not Found
Reading package lists... Done
E: Some index files failed to download, they have been ignored, or old ones used instead.


I tested several mirrors and they are all the same, is there any announcement?
