Dec 12: It appears that a large number of users preferentially hit server 1, despite DNS round-robin. Some reports indicate that this may be caused when there is a Microsoft DNS server in between us and the end user (e.g. at the ISP.) Therefore, if you use rsync against our servers, you may want to hit server 2 explicitly (rsync2.kernel.org or mirrors2.kernel.org). Similarly, you might find that you get better performance from www2.kernel.org, ftp2.kernel.org or git2.kernel.org.
I never looked at this news before as it is very rarely being updated. Well, at least there has been some mirrors who provide faster access to the latest kernel version.
