So I don't see anything about your report that looks particular
troublesome.

What sorts of speeds do you get from a clone? I think I'd define a
problem as:

 - Cloning from git.kernel.org at > 200KiB/s
 - Cloning from git.gnome.org at < 100KiB/s

(If there is some problem that affects connections to both
git.kernel.org and git.gnome.org, then I assume better networking minds
then us will be working on it.)
