The kernel.org web servers are back on line and are once again delivering the Git repositories of some Linux developers – including the main repository of the development branch of Linux maintained by Linus Torvalds. However, the frontpage links to the archives with the sources for the Linux kernel point to files that have yet to be uploaded. Following four weeks of downtime, kernel.org is thus at least partially back in business. The administrators took the servers offline for maintenance work around a month ago, following the discovery in late August that an attacker had obtained access to some servers.
