archives.gentoo.org seems to only list messages from mid-2012 and earlier. Compare: http://archives.gentoo.org/gentoo-catalyst/ with http://news.gmane.org/gmane.linux.gentoo.catalyst I think that Gmane does a good enough job that it's not worth running a browsable archive interface in-house, and archives.gentoo.org/<project>/ should redirect to http://dir.gmane.org/gmane.linux.gentoo.<project>. Obviously, the mlmmj archives should be preserved in case Gmane suddenly disappears, but in the mean time, maintaining in-house archives seems like a waste of time. Reproducible: Always
From http://archives.gentoo.org/gentoo-dev/: Note: Due to technical difficulties, the Archives are currently not up to date. GMANE provides an alternative service for most mailing lists. c.f. bug 424647 *** This bug has been marked as a duplicate of bug 424647 ***
