[coreboot] Accessing Repository via http fails

[Bao, Zheng]

Hi, Stefan & folks,
Is it just me or do you guys have the same problem when clone the code via http?
#git clone http://[<username>:<password>@]review.coreboot.org/p/coreboot.git
Initialized empty Git repository in /home/baozheng/LinuxBIOS/temp/coreboot/.git/
error: The requested URL returned error: 503 while accessing http://zbao:[e-mail]/p/coreboot.git/info/refs

fatal: HTTP request failed

Any thing wrong?

Zheng
