The CentOS team is happy to announce the availability of CentOS-4.0 (RC1) for x86_64. This product supports AMD Opteron, AMD Athlon64, AMD AthlonFX and Intel EM64T CPU based computers.

A bittorent for the 4 CD binary installation set (in .iso format ) is available from:


The only way to download ISO's is via bittorrent. Please leave your download client running after the download is complete (with ports 6881-6889 open) as your client will become part of the peer to peer bittorrent network and reduce the load on our network mirrors. If you need some quick pointers for getting up to speed on bittorrent read:


The mirrors that host the OS tree are currently syncing. However, the BitTorrent is live now.
