Re: Released modules sometimes newer on metacpan.org than on cpan.org?!

This to me sounds like you're using a mirror server that hadn't been updated with the newer version yet.

I use cpanm (App::cpanminus) so I'm not sure how to go about troubleshooting your specific issue, or updating the list of mirrors.

stevieb, thanks for the reply. My setup, using cpanplus for installing modules to CygwinPerl, has just used the default. We no longer set up remote mirrors for cpan clients, whether they are are CPAN.pm, CPANPLUS, or cpanminus. As discussed at log.perl.org, here's what happened:

Furthermore, www.cpan.org was pointed at a global CDN, meaning that traffic could be routed efficiently without client configuration. The CDN also meant that users wouldn’t need to worry about out of date or down mirrors.

I have to admit that I don't know what a CDN is, but the meaning is clear enough. A remote mirror that's slow to update shouldn't be a problem. However, my local mirror could be. I'm going to check now.

Here's my settings; one uses s mirrors in the cpanplus shell:

CPAN Terminal> s mirrors

Readonly list of mirrors (in order of preference):

        1 http://192.168.1.7/minicpan
        2 http://www.cpan.org

Yes, my local mirror at 192.168.1.7 was out of date. I would like to punch myself. I need to make a cron job or something similar for this mirror. Sorry, everyone.

Lucky you.

Content Delivery Network. Basically, traffic is automatically directed to local caching and/or mirroring proxies. You might have heard of Cloudflare? They're a king in that industry.
