Ban a specific mirror in dnf

[Suvayu Ali]

Hi,

I would like to ban a particularly slow mirror[1].  It's the closest
mirror to my geographical location (one of only two mirrors in my
country, India).  Every time I see a bad download error message from
that mirror, everything subsequent to that speeds up and uses the full
capacity of my connection.  How can I achieve this?

Also, is there a way to report this?  Mirrormanager shouldn't even be
listing this mirror, it considerably degrades the user experience.

Thanks,
