Weekend Outage

You may have noticed that some services were unavailable this weekend.  Email continued to flow, and no data was lost.

The short version of the story is that we were bitten by this bug. and learned a lot about how Kubernetes works while we figured out what the issue was.

Sorry for any inconvenience!

CPAN Mirror List Changes

We sent the below email to all the CPAN Mirror contacts yesterday:

An Important Update about the CPAN Mirror List

You're receiving this email because you're listed as a contact point for a CPAN mirror. Thank you! The mirror network has been a huge part of CPAN’s success. Soon, the way clients use CPAN mirrors is changing. You don't need to do anything, but after reading this email, you might want to.

Some background: For a long time, when the CPAN client (aka started up for the first time, it prompted users to configure it by picking a nearby mirror. The assumption was that it would be best to find a geographically nearby mirror. This necessitated the keeping of a central list of mirrors which the client could retrieve and offer as a menu. That's the CPAN Mirror List, maintained by the Perl NOC.

In 2011, the client changed behavior to configure itself automatically, meaning that most new users never saw this list. Furthermore, 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 The CDN also meant that users wouldn’t need to worry about out of date or down mirrors..

After ten years of CPAN defaulting to the CDN, we are going to stop maintaining the mirror list. It will still be present, but have only one entry: This means that anyone attempting to pick a mirror from the list will only find this one option. The mirror status site will be replaced with a static page. As has always been the case, the CPAN client can be configured manually to use any mirror, whether or not it's on the mirror list.

Users who have configured their CPAN clients to point at your mirror will continue to hit it. No new users are likely to find it -- but after all, they were already very unlikely to do so! That said, you do not need to shut down your mirror. If you use your mirror, you can keep mirroring. We’re not removing or changing the ability to mirror. If you know you have users of your mirror who would like to keep using it, please feel free to keep mirroring it.

On the other hand, if you would like to stop mirroring CPAN, feel free to do that, too. Clients have always had to deal with their mirror going away, and they will be fine if you choose to shut down your mirror.

We have not set a firm date for the emptying of the mirror list, but we expect it to happen no earlier than mid-February and no later than June 2021.

If you have any questions, please email us at <cpan at>.

Finally: Thanks! The mirror network helped make CPAN practical for many years, and CPAN helped make Perl a success. You were part of this endeavor, and we appreciate it!
