Rsync will just hang waiting for a connection that never happens if ipv6 connection is attempted. My ISP is ipv6 only with a 464xlat translation to get to ipv4 servers, using ipv4 addresses work file for this mirror. Reproducible: Always Steps to Reproduce: 1. Have ipv6 ISP 2. sync from rsync://rsync.gtlib.gatech.edu/gentoo 3. watch as hangs, adding -4 to rsync command prevents this. Actual Results: Just do: rsync -6 rsync://rsync.gtlib.gatech.edu/gentoo /tmp/test --stats -av and compare with rsync -4 rsync://rsync.gtlib.gatech.edu/gentoo /tmp/test --stats -av Expected Results: Ipv6 should work if this page is right: https://www.gentoo.org/downloads/mirrors/#US But this page and my testing suggests it's ipv4only as this page suggests: https://www.gentoo.org/support/rsync-mirrors/

Georgia Tech: could you take a look please? I've dropped it as IPv6 for now in our listing but that won't help entirely because of the AAAA record being published.
The AAAA records are gone now: $ host rsync.gtlib.gatech.edu rsync.gtlib.gatech.edu has address 128.61.111.9 rsync.gtlib.gatech.edu has address 128.61.111.7
Finally! While it would be better if they could support modern internet this resolves the reason for the report, it helps.
