As part of improvements to download.opensuse.org experience, currently new pilot service is available for using with zypper.

https://mirrorcache.opensuse.org

Its primary task is to redirect zypper requests to a mirror in client's country, similar to what MirrorBrain project does.

You can try to replace in /etc/zypp/repos.d/*.repo

http://download.opensuse.org

with

http://mirrorcache.opensuse.org

or

https://mirrorcache.opensuse.org

Since it is still a pilot, the service comes without any guarantee or obligations.

Reasons when you may want to try it:

- you want to stick to https connection (mirrorcache will try to find a mirror in your country, which supports https, if available).

- you are on ipv4-only or ipv6-only connection (mirrorcache will try to find a mirror which supports ipv4 or ipv6, depending on the request's connection);

- in case when download.opensuse.org (d.o.o) is temporary unavailable;

- redirection from d.o.o leads to a mirror, which actually doesn't have the requested file (it is rare, but can happen);

Additional reasons:

- you want to help with improving d.o.o experience and provide feedback;

- you are interested in mirror management, for which admin's UI is available, and non-admin UI is planned (so a user can add and manage own mirror without global admin rights);

  https://mirrorcache.opensuse.org/app/server

  (login using UI menu and ask me for admin rights if you want to use it or see more advanced controls, like job details).

- you need some related functionality: it is possible that it can be easily achievable with mirrorcache.

How caching works:

- caching happens on folder level, so e.g., when zypper tries to access file, unknown for mirrorcache - it will be redirected to d.o.o, then a background job will collect info about mirrors. Thereafter further requests to the same folder will be properly redirected to a mirror in the client's country, honoring http/https scheme and ipv4/ipv6 connection used:

- requests to remodata/repomd.xml is not cached, so zypper always gets the latest version of packages.
