[CentOS-mirror] Some IPv6 mirrors not reachable by IPv6

Hi fellow mirror admins.

I made a list of mirrors that have a published AAAA record, and checked 
if those mirrors are actually reachable by IPv6. Unfortunately it looks 
like there is a significant amount of mirrors that do have an AAAA 
record, but the actual services (http, ftp, rsync) are not available by 
IPv6.

Here is the list:

The ones marked FAIL are mirrors which have an AAAA record but are not 
reachable by IPv6. My tests were done primarily from AS 29422, with some 
spot checking from ASs 29169 and 16276.

If you have concerns/doubts about some specific server's test results, 
feel free to contact me off-list for more details and/or more tests.
