Hello,

I see that ftp.pbone.net is not listed as a mirror for CentOS 6 updates 
for x86_64 arch.
curl -4 --silent 
'http://mirrorlist.centos.org/?release=6&arch=x86_64&repo=updates&infra=stock'

But for i386 arch is listed:
curl -4 --silent 
'http://mirrorlist.centos.org/?release=6&arch=i386&repo=updates&infra=stock'

http://centos2.hti.pl/6.6/updates/i386/
http://ftp.ps.pl/pub/Linux/CentOS/6.6/updates/i386/

For x86_64 base system and other CentOS versions ftp.pbone.net is listed 
as a mirror.
Could you point me what is wrong with CentOS ver. 6 x86_64 updates on 
ftp.pbone.net ? What should I fix ?

Best regards.
