[H2] Donating/sponsoring servers to the CentOS Project
We mainly use donated/sponsored servers as mirrors we control/monitor. If you can host one (or more) dedicated servers, here are the preferred specifications :
Recent Intel and AMD physical machines ( supporting x86-64-v2 specs, aka grep sse4_2 /proc/cpuinfo)

4000GB drive (raid-1, 2x4000GB preferred, or higher : if using megaraid_sas or mpt3sas adapter, a recent one that would be supported by el9 kernel)

8GB RAM (>= 8GB preferred)
Gbit/sec internet connection (with ipv6 connectivity, so dual-stack)
a substantially unlimited outbound monthly bandwidth (we can easily average about 15TiB per machine currently per month on some machines)
Server can be set up with a minimal base install of the current ‘latest’ release, and either a password, or a ssh public key for root access send through that email address, and we will handle an initial audit/reinstall, and slotting into our management and monitoring framework from there
(!) Note: The vast majority of our dedicated servers are in the USA (which we greatly appreciate ... and we can use more there). We have a great need for providers from Europe, Asia, Africa, South America, and the Asia Pacific region to step up and donate dedicated servers as we now have an update system that can balance loads geographically.
(!) Note: If you are an ISP and provide a dedicated server which we can use as a mirror, the CentOS project will manage that server. We will maintain it as an up to date mirror that your local CentOS machines can all use. The end result might be that your users get faster updates
(!) Note: Virtual machines are rarely up to the loads the project's uses can place upon them. However, if you can contribute something that you think is at par with the above mentioned performance level, we would be happy to test it. We might still be able to find use for them within the CentOS Infrastructure.
If you think that your proposal would match these requirements, or that you think you can offer something to the CentOS Project infra, feel free to contact us at donate@centos.org

CentOS invites you to be a part of the community as a contributor.
There are many ways to contribute to the project, including documentation, QA,
testing, coding changes for SIGs, providing mirroring or hosting,
and helping other users.
How to verify your ISO.
If you plan to create USB boot media, please read this first to avoid damage to your system.
The CentOS Stream 10 release notes are continuously updated to include issues and incorporate feedback from users.
[H2] Cloud and container images
We build, maintain and update Cloud images that you can find on our Cloud Images server.
These images are built and made available for all the architectures that corresponding version supports.
People interested in importing ‘GenericCloud’ images into their own cloud solution can find corresponding images on the link above.
Worth knowing that you can also import (through Skopeo or other methods) container images the same way, and such .tar.xz files can be found on the same mirror.
Parallel to that, we have also official images that are available directly to be deployed for the following solutions:
Amazon Web Services
Quay Registry
Docker Registry
[H2] Geographical mirrors
If you’re looking for a specific (or geographically local) mirror, please check out our list of current mirrors.
[H2] Sources
CentOS Stream sources are maintained in the
centos-stream GitLab namespace.
CentOS SIG sources are maintained in several locations:
CentOS namespace on GitLab
CentOS namespace on GitHub
[H2] Older Versions
Legacy versions of CentOS are no longer maintained.
They are available from the CentOS Vault for historical purposes.
