My /var/log/emerge-fetch.log is full of errors like: Resolving distfiles.gentoo.org (distfiles.gentoo.org)... 2a00:8a60:e012:a00::21, 2600:3402:200:227::2, 2600:3404:200:237::2, ...

Connecting to distfiles.gentoo.org (distfiles.gentoo.org)|2600:3402:200:227::2|:80... connected. I'm setting the severity to high as being a timeout it slows down emerge significantly when lots of small files are not found on local mirrors as that particular ip gets picked first every time. Reproducible: Always
It works fine for me, but we have seen other reports of IPv6 routing trouble recently. Not much we can do about internet backbone trouble.
Ok, I ran a tracepath and the last hop it reaches is 2001:638:c:a100::2(kr-aah15.x-win.dfn.de). Acording to whois that is a router of the "German National Research and Education Network" so I suppose the "RWTH Aachen University" hosting the Gentoo mirror has some way to contact them and you have a way to contact that university's sysadmins?
Btw, doesn't seem to be an IPv6 only issue, IPv4 address is unreachable as well, though it clearly reaches the university's network. So most likely the server is just dead: 4: 10.220.133.105 34.674ms asymm 6 5: cr-fra1-be1.x-win.dfn.de 33.662ms 6: kr-aah15-0.x-win.dfn.de 37.469ms 7: fw-xwin-1-vl106.noc.rwth-aachen.de 38.030ms asymm 8 8: n7k-ww10-1-vl158.noc.rwth-aachen.de 37.391ms asymm 9 9: no reply 10: no reply 11: no reply 12: no reply 13: no reply 14: no reply 15: no reply 16: no reply 17: no reply 18: no reply 19: no reply 20: no reply 21: no reply 22: no reply 23: no reply 24: no reply 25: no reply 26: no reply ^C
