Why would a YUM repository block an IP address ?

[eva2000]

Was testing some new functionality in Centmin Mod on my local Virtualbox server on my PC. But seems one of the included CentALT YUM repositories was getting Error 14 bad address on running YUM. I thought that http://centos.alt.ru/ was down.

But checking at http://www.downforeveryoneorjustme.com/http://centos.alt.ru/

I get

It's just you. http://centos.alt.ru is up.

So using a proxy i can view centos.alt.ru fine. How did I end up having my home ISP IP banned ??? Just unlucky that my ISP IP was amongst a block of bad IPs  ?

First time this has happened for me

Anyone else not able to visit and access http://centos.alt.ru/ ?

I can access the site just fine. How much testing are you doing? Are you pulling a ton of packages off of the repo?

Turn off IPv6 and try again.

Thanks guys, I actually haven't installed any CentALT packages only the release RPM itself. 

I emailed Denis from CentALT and he did a traceroute from his end to my ISP IP and looks like getting 100% packet loss entering the Australian network side.
