As you may already know, kernel.org site which hosts the Android git repository has been hacked. Because of this we can't obtain the Android source code from its servers. All attempts to do so ultimately fail with the similar response:
[root@localhost WORK_DIRECTORY]# repo sync
android.git.kernel.org[0: 149.20.4.77]: errno=No route to host
android.git.kernel.org[0: 149.20.20.141]: errno=Connection timed out
fatal: unable to connect a socket (Connection timed out)
or:
[root@localhost ~]# curl https://android.git.kernel.org/repo> ~/bin/repo

curl: (7) couldn't connect to host
I will describe another way to get the Android source codes if you hadn't already cloned it's repo before kernel.org servers went down.
Prepare the environment
First, you need to download "repo" script from kernel.org my blog (please, enclose the URL address in double quotes):
curl "http://php.webtutor.pl/en/wp-content/uploads/2011/09/repo" > ~/bin/repo
chmod a+x ~/bin/repo
PATH=~/bin:$PATH
Download the Android repository
Now, you can safely download the repository, like so:
mkdir WORK_DIRECTORY
cd WORK_DIRECTORY
repo init -u git://codeaurora.org/quic/qrd-android/platform/manifest.git -b refs/tags/R8625QSOSKQLYA3020 -m default.xml
repo sync
