anoncvs2.us.netbsd.org: how frequently updated?

I'm using anoncvs2.us.netbsd.org, trying to be helpful by not
loading anoncvs.netbsd.org.

I'm curious how often anoncvs2.us.netbsd.org is updated, though.  As
of a couple minutes ago, on the netbsd-3 branch, it had a

  src/x11/lib/Makefile

that referenced a "dmx" subdir -- version 1.5.4.1 of this file, as
seen here:

  http://cvsweb.netbsd.org/bsdweb.cgi/src/x11/lib/Makefile?rev=1.5.4.1&content-type=text/x-cvsweb-markup&only_with_tag=netbsd-3

But the 5-minutes-newer subdir "dmx", as seen here:

  http://cvsweb.netbsd.org/bsdweb.cgi/src/x11/lib/dmx/Makefile?rev=1.1.2.1&content-type=text/x-cvsweb-markup&only_with_tag=netbsd-3

does not exist on the mirror, thus breaking the netbsd-3 x11 build.

At this point, the files in question are more than 24 hours old.  Is
the mirror synced once per day?  Even less frequently?  Perhaps I'm
overlooking something simple?
