ftp.pld-linux.org unreachable via IPv6

[Jacek Konieczny]

ftp.pld-linux.org resovles to IPv4 and IPv6 addresses:

# host ftp.pld-linux.org
ftp.pld-linux.org is an alias for ftp3.pld-linux.org.
ftp3.pld-linux.org is an alias for ftp.agmk.pld-linux.org.
ftp.agmk.pld-linux.org has address 91.192.224.120
ftp.agmk.pld-linux.org has IPv6 address 2001:6a0:159::120


And the IPv6 address is unreachable via a sixxs tunnel:

IPv6 connectivity should be fixed or the AAAA record removed, otherwise one
needs to force IPv4 connection to install packages.

I have been broken for a few days.
