Anonymous read-only Git access

[yilu@bupt.edu.cn]

Hi,everyone
I want to get the GCC-10 source and I followed the instructions in https://gcc.gnu.org/git.html, however, the command
git clone git://gcc.gnu.org/git/gcc.git SomeLocalDir
cannot work. 
And I found I cannot connect https://gcc.gnu.org/git/gcc.git even without firewall(I'm in China). I got a 403 Forbidden
 "You don't have permission to access /git/gcc.git/ on this server."
 "Apache Server at gcc.gnu.org Port 443".  
What can I do in this situation? 
Thanks.
