I am a user from china. I find that after I run “sudo cachyos-rate-mirrors”, I cannot sync with arch repo. I find the first line of /etc/pacman.d/mirrorlist “Server = https://archlinux.cachyos.org/repo/$repo/os/$arch” is uncommented. After comment it, I can sync with arch repo, is it a bug of cachyos-rate-mirrors?
I have no issues on my side, but perhaps maybe a pacnew file?
But I’m Stateside (US) so that may come into play. 
Just short clip from mine:
sudo cachyos-rate-mirrors
[sudo] password for me:

Hello and welcome,
I dont think this is a valid mirror?
Which does still raise the question of where it is coming from.
I cant manage to get rate-mirrors (which cachyso-rate-mirrors uses) to produce that mirror and the URL is not navigable in the browser.
This line seems to be inserted by “cachyos-rate-mirrors” instead of “rate-mirrors”. I found the line 119 to 122 of /usr/bin/cachyos-rate-mirrors is
“# Always insert CDN77 mirror to the start, unless RU region is detected
if ! check_ru_location; then
sed -i ‘1iServer = https://archlinux.cachyos.org/repo/$repo/os/$arch’ “${MIRRORS_DEFAULT_DIR}/mirrorlist”
fi”
I am not in Russia, so the script insert this line. But that let pacman cannot sync with archlinux mirror in China.
Ah yes.
I recall a mirrors labeled CDN77 being a problem but I didnt notice this part of the script.
I am also not in russia .. and dont have any matching lines in any of my mirrors.
And that specific URL returns a 404 while not being present in current lists of the mirrors, ex;
https://raw.githubusercontent.com/CachyOS/CachyOS-PKGBUILDS/master/cachyos-mirrorlist/cachyos-mirrorlist
You can safely omit/comment it out for now, but for a systemic change we will need to get cachyos-rate-mirrors to change..
Thanks for your help! I will comment that line in /etc/pacman.d/mirrorlist.
To follow up I have opened an issue for this;
and as there is also a desire to expand cachyos-rate-mirrors with protocol functionality I may follow it up with a PR in the near future.
