We'll try to get to the bottom of this, but not until working hours,
which in the US starts on Tuesday this week.

There is no centralized collation of statistics; mirrors are listed at
but this list might be out of date and not comprehensive (there are
instructions for creating mirrors, and no requirement that someone who
creates a mirror, e.g., for internal use, report this to us), and there
is no requirement for mirrors to collect download statistics.
