TL;DR: Check if your mirror is listed on http://orava.miuku.net/tmp/inaccessible_centos_urls.txt

---

Hi, it's me again. I wrote back in March that many FTP and rsync mirror URLs had various problems, but that I'd save those for some later posting. Now might be a good time to get those taken care of.

Looks like some mirrors have changed their paths for CentOS content:

old: ftp://mirror.millry.co/CentOS/ new: ftp://mirror.millry.co/

old: ftp://mirror.nsw.au.glovine.com.au/CentOS/ new: ftp://mirror.nsw.au.glovine.com.au/centos/

old: ftp://mirror.thelinuxfix.com/CentOS/ new: ftp://mirror.thelinuxfix.com/centos/

old: ftp://mirror.vcu.edu/pub/gnu+linux/centos/ new: ftp://mirror.vcu.edu/pub/gnu_linux/centos/

old: rsync://centos.mirrors.atwab.net/shares/ new: rsync://centos.mirrors.atwab.net/centos/

old: rsync://centosmirror.go4hosting.in/centos/ new: rsync://centosmirror.go4hosting.in/out/

old: ftp://mirror.denit.net/centos/ new: ftp://mirror.denit.net/

In addition to these, I found a number of cases where the mirror's ftp or rsync port was unreachable. I emailed some of those mirror admins (those whose email address I was able to find easily) and some of those problems got cleared. Thanks to everyone who fixed things :)

The admin of mirrors.hustunique.com said that the mirror should be removed from the mirrorlist due to problems with their campus network. Note that http://mirrors.hustunique.com/centos/ has been a redirect to some other mirror for a long time now, so having mirrors.hustunique.com listed serves no useful purpose at the moment.

ftp://mirrors.gigenet.com/centos/ and rsync://mirrors.gigenet.com/centos/ should be removed. Their support said they only support HTTP at the moment.

ftp://mirror.aarnet.edu.au/pub/centos/ is no longer accessible. In a previous communication I had with them they said they're phasing out FTP support, and now it looks like it's gone.

rsync://centos-distro.cavecreek.net/CentOS/ points to centoss7.centos.org, and the CentOS rsync module is not accessible. Perhaps this rsync entry should be removed from the public mirrorlist.

For various reasons (ftp/rsync port not listening or firewalled away, login incorrect, path not found etc), the following FTP and rsync URLs are still inaccessible: http://orava.miuku.net/tmp/inaccessible_centos_urls.txt

The script checks each inaccessible mirror URL three times per day, and if an URL works, it is removed from the list of URLs to be checked. The script has been running for two weeks now. Therefore the listed URLs have been inaccessible for at least two weeks.

If your mirror is listed, please fix the problem and wait 8 hours to see if it disappears from the list. If it disappears from the list, everything's fine and you don't need to email anyone that you've fixed it. If you change the URL where the CentOS content is stored, please send an email to this mailing list. I can't make changes to the list of mirrors myself. Please also make sure your mirror is accessible from outside your network. Firewall problems seem to be common.

If you have questions about the testing procedure, feel free to contact me.

If those URLs stay inaccesible for an extended period of time, I would suggest removing those URLs from the list of CentOS mirrors, https://www.centos.org/download/mirrors/
