Some Austrian mirrors will be taken down soon due to very low activity.  So remove them from the mirror list:

- www2.at.FreeBSD.org
- ftp2.at.FreeBSD.org
- cvsup2.at.FreeBSD.org

Additionally note that:
- www.at.FreeBSD.org
- ftp.at.FreeBSD.org
- cvsup.at.FreeBSD.org

should now have a valid/complete valid IPv6 entry/configuration.
