The link http://downloads.sourceforge.net/boost/boost_1_63_0.tar.bz2
redirects to http://downloads.sourceforge.net/project/boost/boost/snapshots/master/boost_1_63_0.tar.bz2
which seems to be a snapshot from master, and VERY different to the
boost_1_63_0 release (which makes it a VERY misleading URL).

How often is that snapshot updated?

Shouldn't it have a different name if it's not boost_1_63_0.tar.bz2
but some completely different set of sources (which currently don't
even build)?

The Fedora Linux packages have been using that URL, for several years
by the look of things. So I have no idea what arbitrary collection of
changes we've been shipping instead of a proper release.
