It is generally a better idea to not force the use of a specific 
protocol but let rsync pick the best available protocol. This tends to 
be IPv6 if available. We may not necessarily have an IPv6-enabled msync 
node on all continents all the time and in these cases we're forced to 
use only IPv4 for requests from that continent. Asia, South America and 
Africa are typically affected by this (donated nodes are welcome if you 
can help with this, see https://wiki.centos.org/Donate )


That said, 2a06:afc0::21 seems to be available from here:

$ rsync rsync://[2a06:afc0::21]/CentOS/

msync.CentOS.org rsync service (centose5)
---------------------------------------

This service is intended for the sole use of the CentOS worldwide mirror 
network to synchronize mirrors.

2401:78c0::2, on the other hand, seems to be down. Fabian may need to 
remove that address from rotation. Thanks for the notice!
