cvs access to gnulib?

[Karl Berry]

Was the cvs access to git intentionally shut down?
(Sorry if I missed the announcement.)
As of some time ago -- looks like it might have been six months, call me
late! -- I am seeing:

    cvs [update aborted]: connect to [pserver.git.sv.gnu.org]:2401 failed:
    Connection timed out

That is, :pserver:address@hidden:/gnulib.git.

Alternatively, is it possible to tell git "I only want to clone one
subdirectory" (namely build-aux)?  All the incantations I tried failed.

Thanks,
karl
