In China, cannot "opkg update"

Probably blocked by Chinese GFW
any working mirror ?
I cannot install VPN yet because I can't install the basics

I get the folowing

opkg update
Downloading http://downloads.lede-project.org/releases/17.01.0/targets/brcm2708/bcm2710/packages/Packages.gz
Failed to establish connection
*** Failed to download the package list from http://downloads.lede-project.org/releases/17.01.0/targets/brcm2708/bcm2710/packages/Packages.gz

Comment: new installation, so git , make etc is not installed.
