The subject of download counters for CPAN modules has risen yet again, as it does every few years.
This time around, I'm ready for it.
For the last few years, I've been running http://cpan.strawberryperl.com/
This is not a mirror as such, it is a redirect server that acts as the default CPAN mirror for Strawberry's pre-configured CPAN client. It runs via a simple
It doesn't necessarily provide the fastest mirror, but it does provide something that won't be slow and is assured not to break (unlike the DNS rotation or geo-redirect services, which can't always tell when one of their members breaks).
One of the luxuries of this redirect mechanism is that I have logs, going back about 400 days, of every module that a Strawberry Perl user who is happy to live with the default mirror has downloaded.
If anyone is interested in coming up with a log processor for this data set to build some kind of analysis tool, I'd be happy to provide you with access.
One of the benefits of this is that I can upgrade my CPAN Top 100 lists with demand-weighted scoring, so that we can better map CPAN Testers failures to the actual daily needs of Windows Perl hackers and identify which are the modules that we need to focus the most attention on.
You can find me, or one of the other people with access to the cpan.strawberry logs, in the #win32 channel on irc.perl.org.
