yes, it happened with Xfree86 upgrade. 2 new servers were then introduced in
order to prevent this problem from re-appearing.
However this does not _seem_ to be enough, and I guess it's due to "feature"
of glibc, that sorts IP addresses from numerically lowest one to numerically
highest one (so it spoils attempts for DNS load-balancing), so if any program
is the order of addresses returned via gethostbyname() or getnameinfo(), it
tries them always in the following order:
% getent hosts security.debian.org
so no wonder _if_ 220.127.116.11 is loaded more than other servers.
many times I have to re-try update/upgrade to ask other servers and
18.104.22.168 seems to be the slowest for me.
I tried to discuss this "feature" in debian-glibc list
but first time I did not guess the right problem, then I gave up "solving"
I hope someone will confirm or deny this... I don't know how are debian
security servers loaded... I only know that 22.214.171.124 is usually very
