Yup, I can reproduce this from Germany; but Rackspace seems to be doing
fine, and other nearby IP addresses seem speedy.
Since you're downloading a three-year-old package, you're being
redirected from mirrors.j.o to archives.j.o.
I'm just speculating, but maybe there's a data transfer limit on the
archives server which gets activated if there has been too much traffic,
to avoid excess data transfer costs (as has happened in the past).

Out of interest, why do you need to create a mirror of long-outdated
Jenkins packages?
