Windows Server 8 build 7959 has leaked. This appears to be the first build from Milestone 3 that the public has got its hands on, although it is said to be quite buggy, according to BetaArchive. As always, we must emphasize that this is still very early in Windows 8's development, so try not to start forming your opinion on the OS just yet.
At the time of writing, build 7959 was made available on private FTP sites but at the time of publishing it should be arrive on the usual torrent and file sharing sites. It's also worth noting that build 7959 is a 64-bit server version of Windows 8, and not a client version like the builds that have leaked in the past.

Windows 8 build 7850, the first leaked Windows 8 build, hit the Internet three weeks ago. Last week, Windows 8 Build 7955 was leaked. It all began when Microsoft gave its partners access to Windows 8 builds on Microsoft Connect.
Now we're onto 7959, and while this build is nowhere near ready for public consumption, that's not going to stop thousands from giving it a shot. Because the build number is higher than any other previous leak, we can expect new features to surface as a result.
Although a rumor suggests that Windows 8 will arrive on January 7, 2013, we expect that the operating system will ship in time for the 2012 holiday season. Microsoft has confirmed that Windows 8 will support Intel, AMD, and ARM architectures.
