The Qt Project is currently using a content delivery network based solution for distribution of releases. We have been working to improve distribution of Qt open-source packages and now have the setup available for mirroring. Now we need to get more mirrors before going to production.
The idea is to switch to MirrorBrain based system and away from the current content delivery network based service. The work was started a while ago by Daniel Molkentin and now we have the setup available for mirroring. It is very much similar to what KDE is already using, so for many it is quite familiar. At this point I would like to thank Danimo and others from KDE for all the help provided to enable this.
The system is not yet taken into production use, we need to first have enough mirrors in place. Downloads from the new service work, but the system is not yet up to handle the needed load. Currently we have two mirrors in place, and need more before the new download service can be taken into production use.
The new service is for open-source content only. All the commercial Qt licensees are using a separate system. So it is completely ok for non-profit organizations to become a mirror for Qt Project.
If your organization is willing to become a mirror, please follow the steps in the wiki. Or if you know some organization who already provides mirrors, please ask them to become a mirror for the Qt Project.
We are keenly waiting to get the new download service active as it allows much more flexibility than the current setup. Getting the new system into production is also a prerequisite for providing the new online SDK for the Qt Project.
