Ubuntu – Is medibuntu.org still offered as a package source if it has been shutdown since 2010

apt

When trying an update, my output showed that "Some index files failed to download" and "They have been ignored, or old ones used instead." Have I misconfigured something, or is there a reason why mediubuntu.org is still listed as an option if it has been shutdown? Here is my update:

jeff@bigJeff:~$ sudo apt-get update

I was able to remove it from my sources list following the answer to this post:
How do I remove a broken software source?

This is a wiki last edited October 2013 explaining that it has been shutdown:
https://help.ubuntu.com/community/Medibuntu

Once again, I am just looking to alleviate confusion for novices/newbies to Ubuntu, like myself, and promote good security practices.

Offered by who? Haven't you yourself added the medibuntu repository manually? Removing such repositories is entirely your responsibility.
